We first get the prime factorization of $80000$. $$\begin{array}{rl}80000& =8\cdot 10^4\\ & =2^3\cdot 10^4\\ & =2^3\cdot 2^4\cdot 5^4\\ & =2^7\cdot 5^4\end{array}$$Therefore, we can rewrite $\frac{54317}{80000}$ as $\frac{54317}{2^7\cdot 5^4}$. If we multiply this fraction by $10^7$, the denominator is eliminated entirely. Note that multiplying by $10^6$ is insufficient, so since $10^7$ is the smallest power of ten we can multiply this fraction by to get an integer, there are $\boxed{7}$ digits to the right of the decimal point.
