Found a nice little calculator for polynomial long division at http://www.emathhelp.net/calculators/algebra-1/polynomial-long-division-calculator/.
Simply enter the polynomial to be divided into the dividend box.
Enter the number you want to divide by in the divisor box.
Check the “Show steps” box if you want the steps shown. Leave it empty if you just want the answer without an explanation.
It is fairly self explanatory but if you need guidance on how to enter the numbers using acceptable notation click the “show instructions” tab.
Then click the “calculate” tab to set it to work.
