Long division in base $5$ follows the same format as that in base $10$.

$$\begin{array}{ccccc}\text{multicolumn}2r& & 4& 3& \\ \text{cline}2-512& 1& 1& 2& 1\\ \text{multicolumn}2r1& 0& 3& \downarrow & \\ \text{cline}2-4\text{multicolumn}2r& & 4& 1& \\ \text{multicolumn}2r& & 4& 1& \\ \text{cline}4-5\text{multicolumn}2r& & & 0& \end{array}$$Giving us a final answer of $\boxed{43_5.}$
