$\"7x%5E2%28x%5E2%2B6%29=7x%5E4%2B42x%5E2\"$
\n" ); document.write( "Subtract that from the original polynomial to get a remainder of,
\n" ); document.write( " $\"%287x%5E4-9x%5E2%2B8x%2B9%29-%287x%5E4%2B42x%5E2%29=-51x%5E2%2B8x%2B9\"$
\n" ); document.write( " $\"-51%28x%5E2%2B6%29=-51x%5E2-306\"$
\n" ); document.write( "Subtract that from the remainder,
\n" ); document.write( " $\"%28-51x%5E2%2B8x%2B9%29-%28-51x%5E2-306%29=8x%2B315\"$
\n" ); document.write( "Since the degree of the remainder is lower than the degree of the divisor, stop the long division.
