Be sure you include all "place values" which the dividend represents, even if they are 0.


x+3_____________|__________________________________________________________
_______________|______x^4________0*x^3_______0*x^2________0*x________81
_______________|
_______________|____________________________


x+3_____________|______x^3____________________________________________________
_______________|______x^4________0*x^3_______0*x^2________0*x________81
_______________|______x^4________3x^3
_______________|____________________________


x+3_____________|______x^3____________________________________________________
_______________|______x^4________0*x^3_______0*x^2________0*x________81
_______________|______x^4________3x^3
_______________|____________________________
_______________________0________-3x^3_______0*x^2


x+3_____________|______x^3_______-3x^2_____________________________________________
_______________|______x^4________0*x^3_______0*x^2________0*x________81
_______________|______x^4________3x^3
