What is this problem asking us?
If we divided 36,987 into 5
groups of equal size, how many
would be in each group?
Real Life Example
If Janice has 5 years to repay a
small business loan for $36,987, how
much will she need to pay each year?
How do we solve it?
5 is our divisor
Look at the first number and ask how many
5’s are in 3
There are none, so we ask how many 5’s are
in 36
divisor
How many 5’s are in 36?
Recall your multiplication facts to
find the one that will give an answer
near 36.
5 x 7 = 35
 5 x 7 = 35
 Place the 7 above
the division bar
Subtract 35 from 36
Bring down the next
digit in the dividend
 Now ask how
many 5’s are in 19
 5 x 3 = 15
 Place the 3 above
the division bar
Subtract 15 from 19
Bring down the next
digit in the dividend
 Now we ask how
many 5’s are in 48
 5 x 9 = 45
 Place the 9 above
the division bar
Subtract 45 from 48
Bring down the next
digit in the dividend
 Now we ask how
many 5’s are in 37
5 x 7 = 35
 Place the 7 above
the division bar
Subtract 35 from 37
There are no more
numbers to bring down
The remainder is 2,
which means 2 are left
over
The quotient or
answer to our problem
is 7,397 with a
remainder of 2
Our Real Life Example
If Janice has 5 years to repay a small
business loan for $36,987, how much
will she need to pay each year?
What is this problem asking us?
If we divided 8,437 into 6
groups of equal size, how many
would be in each group?
Real Life Example
Can you think of a word problem that
can be expressed as the division
problem written above?
How do we solve it?
6 is our divisor
Look at the first number and ask how many
6’s are in 8
There is one, so we multiply and begin to
work through the steps to solve the problem.
divisor
 6 x 1 = 6
 Place the 1 above
the division bar
Subtract 6 from 8
Bring down the next
digit in the dividend
 Now ask how
many 6’s are in 24
 6 x 4 = 24
 Place the 4 above
the division bar
Subtract 24 from 24
Bring down the next
digit in the dividend
 Now ask how
many 6’s are in 3
 6 x 0 = 0
 Place the 0 above
the division bar
Subtract 0 from 3
Bring down the next
digit in the dividend
 Now ask how
many 6’s are in 37
 6 x 6 = 36
 Place the 6 above the division bar
Subtract 36 from 37
There are no more numbers to bring
down
The remainder is 1, which means
there is one left over
