What is this problem asking us?
If we divided 682 into 4 groups
of equal size, how many would be
in each group?
Real Life Example
If Grandma has 682 dollars that she
wants to share it equally with four of
her grandchildren, how much will each
grandchild receive?
How do we solve it?
divisor
4 is our divisor
Look at the first number and ask how many
4’s are in 6
Recall your multiplication facts to find the
one that will give an answer near 6.
There is one four in six.
4x1=4
 Place the 1 above
the division bar
Subtract 4 from 6
 Now ask how
many 4s are in 28
Bring down the next
digit in the dividend
 There are no 4’s in 2.
4 x 0 = 0
 Place the 0 above the
division bar
Subtract 0 from 2
There are no more
numbers in the dividend
to bring down.
There are two left over.
remainder
 The answer to the
problem is called the
QUOTIENT.
The QUOTIENT is
170 remainder 2
remainder
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?
divisor
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.
6x1=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
6x0=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
The quotient or answer to our
problem is 1,406 with a remainder of 1
