Contributed by: Knapke
You will use this problem in the next several
 slides as you use long division.
You may wish to write this on paper to avoid
 navigating backwards.
First, you will need to rewrite the problem.
Next, you will need to find the first term in
 your solution.
This goes above
the division bar
Then, you will need to multiply.
This answer will need to be subtracted.
