Polynomial division
How the division algorithm can be used to check the result of the polynomial division.

According to the division algorithm, f(x) and d(x) are the polynomials, where $$d(x)\neq 0$$ and the degree of d(x) is less than or equal to the degree of f(x). Then, there exist unique polynomials q(x) and r(x) such that $$f(x) = d(x) - q(x) + r(x)$$, where the degree of r(x) is zero or of a lesser degree than d(x).
$$\frac{f(x)}{d(x)}=\frac{1(x)+r(x)}{d(x)}$$
$$f(x)=d(x)*q(x)+r(x)$$
