Polynomial Division Calculator

Enter the dividend and divisor coefficients (highest degree first) to perform polynomial long division — with the quotient, remainder, the identity dividend = divisor·quotient + remainder, and full step-by-step working.

Division identity:  dividend = divisor · quotient + remainder
dividend coefficients ÷ divisor coefficients

Enter coefficients highest degree first, comma-separated. Example: 1, -2, -4 means x² − 2x − 4, and 1, -3 means x − 3.
