The resulting polynomial will have coefficients that are rational expressions of input coefficients:
Polynomial quotient over the integers modulo :
Polynomial quotient over a finite field:
PolynomialQuotient also works for rational functions:
The quotient and remainder of division of by are and , where :
and are uniquely determined by the condition that the degree of is less than the degree of :
Applications (2)
When the divisor divides the dividend , then the quotient of by satisfies :
Use PolynomialGCD to check that divides :

For a polynomial f, f==gq+r, where r is given by PolynomialRemainder:
Use Expand to verify identity:
To get both quotient and remainder use PolynomialQuotientRemainder:
PolynomialReduce generalizes PolynomialQuotient for multivariate polynomials:
Use PolynomialGCD to find a common divisor:
Use PolynomialQuotient to see the resulting factorization:
For rational functions common divisors are not automatically canceled:
Cancel effectively uses PolynomialQuotient to cancel common divisors:
The Cyclotomic polynomials are defined as quotients:
Possible Issues (2)
The result depends on what is assumed to be a variable:
The result from PolynomialQuotient depends on recognizing zeros:
