3Vocabulary Words for the parts of the problem quotient remainderdivisor dividendproduct
4Step 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?28 235
5Step Two – Multiply Multiply the divisor by the quotient. Write your answer under the dividend.Think: 2 x 8 = 1628 23516
6Step Three – Subtract Subtract the product from the dividend. Notice you still have a five in the dividend.Think: 23 – 16 = 72167
7Step Four – Bring Down Bring the five down next to the seven. 2 Repeat steps 1 – 3.21675
8Step One -- DivideDecide 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?28 2351675
9Step Two – Multiply Multiply the divisor by the new quotient. Write your answer under the dividend.Think: 9 x 8 = 72298 235167572
10Step 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 = 7229 R 38 2351675723
11Review 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.
