You mean this way: (x^3-x^2-24x-19)/(x+3) .
Rendered looks like .

The process works the same as regular long division; so if you understand long division, you will understand this work. 
 
            x^2      -4x       -12
        ________________________________________
x+3    |    x^3       -x^2      -24x       -19
       |
      |     x^3        3x^2
           _______________
          0           -4x^2    -24x
                      -4x^2    -12x
                      ___________
                      0         -12x        -19
                                -12x        -36
                                 ____________
                                 0          17

The quotient and remainder together mean, the rational expression which the division represents is
.

answer is x^2 - 4x - 12 with a remainder of 17

this is the same as x^2 - 4x - 12 + (17/(x+3))
