Divide the following

Question:

Divide $y^{4}-3 y^{3}+\frac{1}{2} y^{2}$ by $3 y$.

Solution:

$\frac{y^{4}-3 y^{3}+\frac{1}{2} y^{2}}{3 y}$

$=\frac{y^{4}}{3 y}-\frac{3 y^{3}}{3 y}+\frac{\frac{1}{2} y^{2}}{3 y}$

$=\frac{1}{3} y^{(4-1)}-y^{(3-1)}+\frac{1}{6} y^{(2-1)}$

$=\frac{1}{3} y^{3}-y^{2}+\frac{1}{6} y$
