I assume that you want to do long division right?
Start with the given expression
Rewrite the expression like this:
Now the question is: How many times does go into ?
It goes in times. So place over the term .
Now multiply by to get
Reverse the signs of to get (place this underneath the dividend)
Now Add to get:

Now the question is now: How many times does go into ?
It goes in times. Place this term over in the dividend.
Now multiply -8x by to get
Reverse the signs of to get (place this underneath the last polynomial)
Now add to get:
======================================================================
Now how many times does go into ?
It goes in times. Place this over the term in the dividend.
Now multiply 21 by to get
Reverse the signs of to get
Now add to get:
Since does NOT go into . This means that the long division process stops.
So the quotient is and the remainder is
This means that
