Step 9

The expression needs to be subtracted from the dividend, so change all the signs in $81 m^{5} + 0 + 0 + 0 + 0$

										$12 m^{2}$	+	$9 m$
$9 m^{4}$	+	$0 m^{3}$	+	$0 m^{2}$	+	$0 m$	+	$0$		$108 m^{6}$	+	$81 m^{5}$	+	$0 m^{4}$	+	$0 m^{3}$	+	$0 m^{2}$	-	$324 m$	+	$0$
									-	$108 m^{6}$	-	$0$	-	$0$	-	$0$	-	$0$
											+	$81 m^{5}$	+	$0$	+	$0$	+	$0$	-	$324 m$	+	$0$
											-	$81 m^{5}$	-	$0$	-	$0$	-	$0$	-	$0$

Step 10

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

										$12 m^{2}$	+	$9 m$
$9 m^{4}$	+	$0 m^{3}$	+	$0 m^{2}$	+	$0 m$	+	$0$		$108 m^{6}$	+	$81 m^{5}$	+	$0 m^{4}$	+	$0 m^{3}$	+	$0 m^{2}$	-	$324 m$	+	$0$
