# numpy.polynomial.polynomial.polydiv

`numpy.polynomial.polynomial.``polydiv`(c1, c2)

  Divide one polynomial by another.

  Returns the quotient-with-remainder of two polynomials c1 / c2. The arguments are sequences of coefficients, from lowest order term to highest, e.g., [1,2,3] represents `1 + 2*x + 3*x**2`.

  Parameters : | c1, c2 : array_like 1-D arrays of polynomial coefficients ordered from low to high.
  Returns : | [quo, rem] : ndarrays Of coefficient series representing the quotient and remainder.

  Examples

      >>> import numpy.polynomial as P
      >>> c1 = (1,2,3)
      >>> c2 = (3,2,1)
      >>> P.polydiv(c1,c2)
      (array([ 3.]), array([-8., -4.]))
      >>> P.polydiv(c2,c1)
      (array([ 0.33333333]), array([ 2.66666667,  1.33333333]))
