DIVISION OF DECIMALS

• A STEP BY STEP GUIDE

2
STEP 1- SETTING UP THE DECIMALS

• Start out by setting up as a long division
  problems
• 2
  Quotient
• 8 16
• Dividend

Divisor
3
YOUR TURN

• SET UP THE FOLLOWING PROBLEMS IN LONG DIVISION
  FORM
• 1. 144 2
• 2. 16 8

4
SOLUTIONS

• 1- 144 divided by 2 2 144
• 2- 16 divided by 8 8 16

STEP 2-FINDING YOUR DECIMAL PLACE

• When you divide a decimal you have to move the
  decimal in the divisor to the right as many times
  as necessary to make it a whole number! If you
  move the decimal in the divisor 3 times then you
  have to move the decimal in the dividend 3 times!

6
Examples

• 1.5 4.5 Move your decimal
• over once on both the
• the dividend and divisor so it
  looks like

7
Examples

• 15. 45. Move your decimal
• over once on both the
• the dividend and divisor so it
  looks like
• this

8
STEP 3-PLACE YOUR DECIMAL IN THE QUOTIENT

• Now find your decimal place in the dividend
  pop it up directly above into the quotient spot-
  Now Divide!
• 3.
• 15 45. 15 45
