Answer
$-16c^2-20c-25$
Work Step by Step
Re-arranging the order of the terms and leaving space for missing terms, the given is equivalent to
$$
(64c^3+0c^2+0c-125)÷(-4c+5)
.$$
Using the long division method shown below, then
$$\begin{aligned}
&
(64c^3-125)÷(-4c+5)
\\&=
-16c^2-20c-25+\frac{\color{red}{0}}{\color{blue}{-4c+5}}
\\&=
-16c^2-20c-25
.\end{aligned}
$$
