Does McDonald’s
Sell Cheese
Burgers?
So, if you can remember this…

Then you can do this…

Let’s start with an easy one:
678
What’s the first thing we do?

Does McDonald’s Serve Cheese Burgers?
The first thing we do
is DIVIDE!

Let’s Divide:
678
1
Since 6 goes into 7 just one
time, we place a one above
the 7. That was EASY!

But What’s Next?

Does McDonald’s Serve Cheese Burgers?
The next thing we do
is multiply!

678
1
Let’s Multiply:
6
Since 1 times 6 is 6, we place
a 6 below the 7. That was
EASY!

But What’s Next?

Does McDonald’s Serve Cheese Burgers?
The next thing we do
is Subtract!
-

678
1
Let’s Subtract:
6
Since 7 minus 6 is 1, we place
a 1 below the 6.
1

But What’s Next?

Does McDonald’s Serve Cheese Burgers?
The next thing we do is
Compare!

678
1
Let’s Compare:
6
Compare the difference to
your divisor – Is it less? Did
you divide enough?
1
7 ÷ 6 = 1
1 X 6 = 6
7 – 6 = 1

Does McDonald’s Serve Cheese Burgers?
The next thing we do
is Bring Down!

678
1
Let’s Bring Down:
6
Since our 8 doesn’t have
anything under it (like the 7
does), we Bring It Down.
18

And Now We Start From
the Beginning!

Does McDonald’s Serve Cheese Burgers?
The first thing we do
is DIVIDE!

678
1
Let’s Divide:
6
Since 6 goes into 18 three
times, we put a 3 above the 8.

18
3

Does McDonald’s Serve Cheese Burgers?
The next thing we do
is multiply!

678
1
Let’s Multiply:
6
Since 3 times 6 is 18, we put
an 18 below our first 18.
18
3
18

Does McDonald’s Serve Cheese Burgers?
The next thing we do
is Subtract!
-

678
1
Let’s Subtract:
6
Since 18 – 18 is 0, we put a 0
under the 18.
18
3
18
0

When you get to a ZERO,
stop and…

Does McDonald’s Serve Cheese Burgers?
Compare!

678
1
Let’s Compare:
6
If the difference is less than
the divisor, then…
18
3
18
0

...You’re done with your
long division problem!!

So, just remember, if you’re having trouble
with LONG DIVISION,
all you have to remember is…
