In order to get a term on the left like the has to multiply , so let's try:
Unfortunately now the right hand side (RHS) is:
We don't want the . So let's modify the 'something'. We have to multiply the by to get a .
So the equation is now
We've added an term and an term. The last term to add is a constant term.
Can you find the last constant in the right hand side? Whatever is left over is the remainder in your division.
