4
Step One -- Divide Look at the first two digits of the dividend. Decide how many times the divisor can go into the dividend without going over. “Twenty-three can be divided into two equal groups of eight with some left over.” Think: How many times can 8 go into 23 without going over?

5
Step Two – Multiply Multiply the divisor by the quotient. Write your answer under the dividend. Think: 2 x 8 =

6
Step Three – Subtract Subtract the product from the dividend. Notice you still have a five in the dividend. Think: 23 – 16 =

7
Step Four – Bring Down Bring the five down next to the seven. Repeat steps 1 –

8
Step One -- Divide Decide how many times the divisor can go into the new number without going over. “Seventy-five can be divided into nine equal groups of eight with some left over.” Think: How many times can 8 go into 75 without going over?

9
Step Two – Multiply Multiply the divisor by the new quotient. Write your answer under the dividend. Think: 9 x 8 =

10
Step Three – Subtract Subtract the product from the previous answer. There is nothing more to bring down. Your answer becomes the remainder. Think: 9 x 8 = 72 29R

11
Review the four steps Dirty – divide the dividend by the divisor. Monkeys – multiply the quotient by the divisor and write the answer under the dividend. Smell – subtract the product from the dividend. Bad – bring down the next part of the dividend and repeat steps 1 – 3.

Your Turn Watch Mrs. Bauer solve the next few problems. Copy each step as she does it. Rehearse in your mind the four steps. Try it on your own.
