Is that supposed to be 24x^2 at the top and 32x^2 ... at the bottom ?
yes
Just visit calc101.com and click on the long division button. Enter your expressions and see all the details.

Polynomial division is just like regular numeric long division, except that each column represents a power of x, not a power of 10.

You can play around with polynomial division till you feel comfortable doing it yourself.
