Space saver division is like short
division but with larger numbers.
156 ÷ 13 can be written like this:
13 into 26
goes 2
times
exactly
13 into 15
goes 1 time
and 2 left
over to
carry
1 2


156 ÷ 13 = 12
A times table for 13 would
be helpful with this method
Divide 13 into 156.
Start with the digit 1,
but this is not
enough.
Then say, 13 into 15
and continue.
Put the result of
each answer on top
of the line.
Space saver division
480 ÷ 15 can be written like this:
