Are you struggling with long division? Do you want to learn **how to do long division** step by step? Look no further – this article will provide you with a comprehensive guide to the **division method**, ensuring that you become a long division pro!

Long division is a formal method of division often called the bus stop method. It is introduced in Year 6 and is used to divide by larger numbers than the short **division method**. The long **division method** is laid out in the same way as short division, with the dividend under the ‘bus stop’ and the divisor to the left. The quotient, or answer, is written on top. The long division method is most often used when dividing by 2-digit or 3-digit numbers and can be used with or without remainders.

Are you ready to master long division? Let’s dive into the step-by-step process of long division!

# How to Do Long Division?

## The Steps of Long Division

Long division is a step-by-step algorithm used to divide two numbers. It is an important mathematical skill that allows us to find the quotient and remainder when dividing larger numbers.

### Step 1: Divide

Begin by dividing the first digit of the dividend (the number being divided) by the divisor (the number you are dividing by). Write the quotient above the line.

### Step 2: Multiply

Multiply the quotient by the divisor. Write the product below the dividend, lining up the digits with the corresponding place values.

### Step 3: Subtract

Subtract the product from the current digit of the dividend. Write the result below the line, aligning the digits with the corresponding place values.

### Step 4: Bring the Next Number Down

Bring down the next digit of the dividend and write it next to the result of the subtraction. This creates a new number to divide.

### Step 5: Repeat

Repeat steps 1 to 4 with the new number. Continue this process until you have divided all the digits of the dividend.

Let’s see an example of long division in action:

Dividend | Divisor | Quotient | Remainder |
---|---|---|---|

125 | 5 | 25 | 0 |

This example demonstrates dividing 125 by 5. The quotient is 25, and the remainder is 0, indicating that 125 is evenly divisible by 5.

## Long Division with Different Types of Numbers

Long division is a versatile method that can be applied to various types of numbers, including polynomials and numbers with different digit lengths. Whether you’re dividing by polynomials or multi-digit numbers, the steps of long division remain consistent, although additional steps may be involved for longer digits. Long division can also be used with decimals, where the decimal point is brought down and the division process continues as usual.

### Long Division with Polynomials

When dividing by polynomials using long division, the steps are similar to dividing by regular numbers. The goal is to perform polynomial division and simplify the expression as much as possible. Let’s take a look at an example:

Polynomial Division Example |
---|

(4x^{3} + 2x^{2} – 6x – 3) ÷ (2x – 1) |

### Long Division with Multi-Digit Numbers

Long division is commonly used when dividing by 2-digit, 3-digit, or 4-digit numbers. The process follows the same steps as regular long division, but there may be additional steps due to the longer digits. Let’s consider the following example:

Multi-Digit Division Example |
---|

1874 ÷ 23 |

### Long Division with Decimals

Long division can also be used to divide decimals. The decimal point is brought down and the division is continued as usual. Here’s an example:

Decimal Division Example |
---|

12.5 ÷ 3.2 |

## Long Division Word Problems

Word problems provide a practical application for the long division method, allowing students to solve real-world scenarios. These problems often involve situations such as sharing a certain quantity equally among a number of groups or determining the number of groups that can be formed from a given quantity.

By applying the long division method, students can work through these word problems step by step, allowing them to arrive at the correct solution. By following the division process and applying it to the specific problem at hand, students can gain a deeper understanding of how to use long division in different situations.

Practicing word problems not only reinforces the understanding of the long division method but also helps students develop critical problem-solving skills. By utilizing the long division method in a variety of contexts, learners can become proficient in using this mathematical technique to solve a wide range of word problems.

### Example Word Problem

Let’s consider the following word problem:

Samuel has 48 cookies that he wants to distribute equally among 6 friends. How many cookies will each friend receive?

Steps | Description |
---|---|

Step 1 | Divide the total number of cookies (48) by the number of friends (6). |

Step 2 | Keep dividing until there are no more cookies left to be distributed. |

Step 3 | Each friend will receive 8 cookies. |

In this example, the division process allows us to determine that each friend will receive 8 cookies. By applying the long division method, students can confidently solve word problems like these and develop their problem-solving skills in a meaningful way.

## Tips and Tricks for Teaching Long Division

When teaching long division, it is important to review fundamental concepts such as multiplication, division, and place value.
