$(- 6 m^{7} + 20 m^{6}) \div 2 m^{4}$

Step 1

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

$2 m^{4}$

$0 m^{3}$

$0 m^{2}$

$0 m$

$0$

$0$

$0 m^{2}$

$0 m$

$0$

$20 m^{6}$

$0$

Step 10

After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.

									-	$3 m^{3}$	+	$10 m^{2}$
$2 m^{4}$	+	$0 m^{3}$	+	$0 m^{2}$	+	$0 m$	+	$0$	-	$6 m^{7}$	+	$20 m^{6}$	+	$0 m^{5}$	+	$0 m^{4}$	+	$0 m^{3}$	+	$0 m^{2}$	+	$0 m$	+	$0$
									+	$6 m^{7}$	-	$0$	-	$0$	-	$0$	-	$0$
											+	$20 m^{6}$	+	$0$	+	$0$	+	$0$	+	$0 m^{2}$	+	$0 m$	+	$0$
											-	$20 m^{6}$	-	$0$	-	$0$	-	$0$	-	$0$
