## The Four Steps of Written Division: A Comprehensive Guide

Performing written division involves following a set of steps to find the quotient and remainder. Here is a step-by-step guide on how to perform written division:

Step 1: Divide
– Start by dividing the first digit of the dividend by the divisor.
– Write the quotient above or next to the dividend.
– Multiply the quotient by the divisor and write the result below the dividend.
– Subtract this result from the first digit of the dividend.

Step 2: Bring Down
– Bring down the next digit of the dividend.
– Combine this digit with the result obtained in step 1 to form a new number.
– Divide this new number by the divisor and write the quotient above or next to it.
– Multiply this quotient by the divisor and write the result below it.
– Subtract this result from the new number.

Step 3: Repeat
– Repeat steps 2 and 3 until all digits of the dividend have been brought down and divided.

Step 4: Check
– Check your work by multiplying the quotient by the divisor and adding any remainder.
– The result should be equal to the dividend.

Let’s illustrate these steps with an example. Suppose we want to divide 432 by 6.

Step 1: Divide
– Divide 4 (the first digit of the dividend) by 6. The quotient is 0.
– Multiply 0 by 6 and subtract the result (0) from 4. The remainder is 4.

Step 2: Bring Down
– Bring down the next digit, which is 3, to form the new number 43.
– Divide 43 by 6. The quotient is 7.
– Multiply 7 by 6 and subtract the result (42) from 43. The remainder is 1.

Step 3: Repeat
– Bring down the last digit, which is 2, to form the new number 12.
– Divide 12 by 6. The quotient is 2.
– Multiply 2 by 6 and subtract the result (12) from 12. There is no remainder.

Step 4: Check
– Multiply the quotient (072) by the divisor (6) and add any remainder (1).
