Long Division
•Long division is as simple as
memorizing this simple question:
“Does McDonalds

1. Divide
Does
2)94
• Divide 2 into first
number in the dividend.
• Think how many 2’s
will fit into 9.
•Write that number directly
above the number you
divided into.
How many 2’s
will go into 9?
Step 2 in Long Division

2. Multiply
McDonalds
2)94
• Multiply the divisor
times the first
number in the quotient.
• Write your answer
directly under the 9
or the number you
just divided into.

2x4=8
Step 3 in Long Division
3. Subtract
Sell
• Draw a line under the 8.
• Write a subtraction sign
next to the 8.

1
• Subtract 8 from 9.
• Write your answer directly below the 8.

4. Check/Compare to
make sure the
difference is smaller
than the divisor!

1
1 is smaller than 2,
so I’m good!
• The difference needs to be smaller than
your divisor- or you can divide more!
Step 5 in Long Division
4. Bring Down!
-Burgers!

2)94
• Go to the next number in
the dividend to the right of
the 9.
• Bring the 4 down next to the 1.

REPEAT OR FINISHED?
• This is where you
decide whether you repeat
the 5 steps of division.

• If your divisor can divide into your new number,
14, or if you have numbers in the dividend
that have not been brought down, you repeat
the 5 steps of division.
Step 1 in Long Division
1. Divide
Does
• Divide 2 into your new
number, 14.
• Place your answer
directly above the 4
in your quotient.

2)94
• Multiply your divisor, 2,
with your new number
in the quotient, 7.
• Place your answer
directly under the
14.

• Draw a line under the
bottom 14.
• Draw a subtraction sign.
• Subtract & place answer
under the line.

REPEAT OR FINISHED?
• Since there are no more
numbers to bring down
you do not repeat the 5
steps of division.

Quotient
2)94
• The quotient on the top is
your answer.
• Since you have no numbers
left, there is no remainder!
