How to use the Multiples of 10
Division Method
Faribault Public Schools

Mr.H.
Introduction
 Division (repeated subtraction)
 Using the multiples of 10 of the divisor for
an easy way to divide.

Mr.H.
Agenda
 Examples
 Practice problems to do on your white
board

Mr.H.
For a problem like 245 / 5
      First of all write the problem like this
10
20
30
40
50
      Make a list of the multiples of 10 on the
side.

Mr.H.
Then add brackets and your
divisor
10 [5]= 50
20 [5]= 100
30 [5]= 150
40 [5]= 200
50 [5]= 250

Then figure out the
multiples.
Mr.H.
Determine what’s the biggest
one that is equal or less that
what you are dividing into…
10 [5]= 50
20 [5]= 100
30 [5]= 150
40 [5]= 200

40   50 [5]= 250

Draw a line down the side of your problem
Subtract the number you picked from your
problem
Put the multiple of 10 on the outside

20 [5]= 100
Repeat until
30 [5]= 150
less than 1              X        X
40 [5]= 200
times your               X        X

number. If it
is zero you
have no
remainder.         5
Excellent! If
it’s not zero
put R then
that number
after your
4    Add up your
outside total!
