To divide , we need to use polynomial long division

Polynomial Long Division:

                       x^2 -2x - 3
        -----------------------------
x^2-x+2 ) x^4 - 3x^3 + x^2 - x - 15
          x^4 -  x^3 +2x^2
         -----------------
               -2x^3 - x^2 - x
               -2x^3 +2x^2 -4x 
               ---------------
                     -3x^2 +3x - 15
                     -3x^2 +3x -  6
                     --------------
                                 -9

So

which also looks like

remainder -9
