Code:

           x^2 - x - 2 + 3/(x+1)
      ______________________
x + 1 | x^3 + 0x^2 -3x + 1
        x^3 +  x^2
         -------------
            - x^2 - 3x
            - x^2 -  x
             ----------
                   -2x + 1
                   -2x - 2
                   ---------
                         3

I think this site: Polynomial Long Division will help you see the detail in the steps. It's just like long division with numbers.
