To solve the given expression, we need to divide each term in the numerator by the denominator. This involves simplifying the coefficients and reducing the powers of the variables.
Step 1: Simplify the Expression
To simplify the given expression:
\[
\frac{45 c^{8} p^{9} - 40 c^{6} p^{7} + 20 c^{3} p^{4}}{5 c^{3} p}
\]
Step 2: Divide Each Term by the Denominator
Divide each term in the numerator by the denominator \(5 c^{3} p\):
\[
\frac{45 c^{8} p^{9}}{5 c^{3} p} - \frac{40 c^{6} p^{7}}{5 c^{3} p} + \frac{20 c^{3} p^{4}}{5 c^{3} p}
\]
