Hi,
Proceed as if you were doing long divison: In this case it will result in a 
Remainder of  -1

           x^2 - 6x + 9
        __________________________
(x-3) |  x^3 - 9x^2  + 27x - 28
      - (x^3 - 3x^2)
       ---------------
                -6x^2 +  27x
             - (-6x^2 +  18x))
                --------------
                         +9x - 28
                      - (+9x - 27)
                          --------
                                 -1
