Let $a$, $b$, $c$, $p$, $q$, and $r$ be real numbers that satisfy the following three equations:
\begin{align*}
19p + bq + cr &= 0,\\
ap + 29q + cr &= 0,\\
ap + bq + 56r &= 0.
\end{align*}
Suppose that $a \neq 19$ and $p \neq 0$. Find the value of
\[
\frac{a}{a - 19} + \frac{b}{b - 29} + \frac{c}{c - 56}.
\]
