The expression needs to be subtracted from the dividend, so change all the signs in $- 15 x^{3} + 0 + 10 x + 0$

								$6 x^{2}$	+	$x$	-	$5$
$3 x^{3}$	+	$0 x^{2}$	-	$2 x$	+	$0$		$18 x^{5}$	+	$3 x^{4}$	-	$27 x^{3}$	-	$2 x^{2}$	+	$10 x$	+	$0$

											-	$15 x^{3}$	+	$0$	+	$10 x$	+	$0$
											+	$15 x^{3}$	-	$0$	-	$10 x$	-	$0$

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

								$6 x^{2}$	+	$x$	-	$5$
$3 x^{3}$	+	$0 x^{2}$	-	$2 x$	+	$0$		$18 x^{5}$	+	$3 x^{4}$	-	$27 x^{3}$	-	$2 x^{2}$	+	$10 x$	+	$0$

											+	$15 x^{3}$	-	$0$	-	$10 x$	-	$0$
																		$0$

Since the remander is $0$ , the final answer is the quotient.

$6 x^{2} + x - 5$
