(x^5  - 5x^4  + 6x^3  - 5x^2  + 16x  - 3) : (x - 3)  =  x^4 - 2x^3 - 5x + 1  
 x^5  - 3x^4                            
 ———————————————————————————————————————
      - 2x^4  + 6x^3  - 5x^2  + 16x  - 3
      - 2x^4  + 6x^3                    
      ——————————————————————————————————
                      - 5x^2  + 16x  - 3
                      - 5x^2  + 15x     
                      ——————————————————
                                  x  - 3
                                  x  - 3
