Solve for V
\left\{\begin{matrix}V=\frac{a}{b}\text{, }&b\neq 0\\V\in \mathrm{R}\text{, }&a=0\text{ and }b=0\end{matrix}\right.
Solve for a
a=Vb

bV=a
Swap sides so that all variable terms are on the left hand side.
\frac{bV}{b}=\frac{a}{b}
Divide both sides by b.
V=\frac{a}{b}
Dividing by b undoes the multiplication by b.
