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

ab=S
Swap sides so that all variable terms are on the left hand side.
ba=S
The equation is in standard form.
\frac{ba}{b}=\frac{S}{b}
Divide both sides by b.
a=\frac{S}{b}
Dividing by b undoes the multiplication by b.
