Steps in Dividing Decimals

1. Make the divisor (outside number) a whole number
   by moving (swingin) the decimal to the right as
   many places as it takes to make it a WHOLE
   NUMBER.
2. In MONKEY TERMS Whatever the outside monkey
   does (how far it swings) the inside monkey does
   also. Then the monkey climbs up and sits on the

What is actually happening . . .

• When you move the decimal one place to the right
  to create a WHOLE number you are actually
  multiplying it by 10!

  to create a WHOLE number you are actually
  multiplying it by 100!
