Understanding Long Division: A Comprehensive Guide
Long division is a mathematical operation that allows us to divide a large number (dividend) by a smaller number (divisor) to find the quotient and remainder. It’s an essential skill for students to master, as it’s used in various mathematical operations, such as fractions, decimals, and algebra. In this article, we’ll explore the concept of long division, its steps, and provide printable worksheets for practice.
The Steps of Long Division
Long division involves several steps, which can be broken down into the following:
- Step 1: Write the dividend and divisor: Write the dividend (the number being divided) on top of a line, and the divisor (the number by which we are dividing) below it.
- Step 2: Divide the first digit: Divide the first digit of the dividend by the divisor, and write the result below the line.
- Step 3: Multiply and subtract: Multiply the result from step 2 by the divisor, and subtract the product from the dividend.
- Step 4: Bring down the next digit: Bring down the next digit of the dividend, and repeat steps 2 and 3.
- Step 5: Repeat the process: Continue repeating steps 2-4 until the dividend is reduced to zero.
- Step 6: Write the remainder: The final remainder is the result of the division.
Example of Long Division
Let’s use the example of 432 ÷ 12 to illustrate the steps of long division:
____________________
12 | 4 3 2
- Step 1: Write the dividend and divisor: We write the dividend (432) on top of the line, and the divisor (12) below it.
- Step 2: Divide the first digit: We divide the first digit of the dividend (4) by the divisor (12), and write the result (0) below the line.
- Step 3: Multiply and subtract: We multiply the result from step 2 (0) by the divisor (12), and subtract the product (0) from the dividend (432). We bring down the next digit (3).
- Step 4: Bring down the next digit: We bring down the next digit (3), and repeat steps 2 and 3.
- Step 5: Repeat the process: We continue repeating steps 2-4 until the dividend is reduced to zero.
- Step 6: Write the remainder: The final remainder is the result of the division (0).
The result of the division is:
36
