divide

(-36y^7 z+19y^7 z^7+24y^7 z^5)/(-4y^2 z^3)

First, we will divide each term in the numerator by the denominator:

(-36y^7 z) / (-4y^2 z^3) = 9y^5 / z^2

(19y^7 z^7) / (-4y^2 z^3) = -19/4 * y^5 * z^4

(24y^7 z^5) / (-4y^2 z^3) = -6y^5 * z^2

Therefore, the final result is:

9y^5 / z^2 - 19/4 * y^5 * z^4 - 6y^5 * z^2
