$\frac{z^{5} - 2 z^{4} - 19 z^{3} - 26 z^{2} - 18 z - 36}{z - 6}$

Step 1

Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of $0$ .

	$z$	-	$6$		$z^{5}$	-	$2 z^{4}$	-	$19 z^{3}$	-	$26 z^{2}$	-	$18 z$	-	$36$

Step 3

Multiply the new quotient term by the divisor.

			-	$z^{5}$	+	$6 z^{4}$
					+	$4 z^{4}$

Step 6

Pull the next terms from the original dividend down into the current dividend.
