Long Division in Algebra

The main things to remember are :

DMSB - the divide, multiply, subtract, bring-down repeated sequence is the same as long division.
If you have something like x³ + 2x²- 12, you have to add in the missing term to make it x³ + 2x² +0x - 12 before you start dividing.
The expressions will always divide in equally. You should not get a remainder.

Practice as many of these as you can.
