`numpy.``polydiv`(u, v)

  Returns the quotient and remainder of polynomial division.

  The input arrays are the coefficients (including any coefficients equal to zero) of the “numerator” (dividend) and “denominator” (divisor) polynomials, respectively.

  Parameters : | u : array_like or poly1d Dividend polynomial’s coefficients. v : array_like or poly1d Divisor polynomial’s coefficients.
  Returns : | q : ndarray Coefficients, including those equal to zero, of the quotient. r : ndarray Coefficients, including those equal to zero, of the remainder.

  Notes

  Both u and v must be 0-d or 1-d (ndim = 0 or 1), but u.ndim need not equal v.ndim. In other words, all four possible combinations - `u.ndim = v.ndim = 0`, `u.ndim = v.ndim = 1`, `u.ndim = 1, v.ndim = 0`, and `u.ndim = 0, v.ndim = 1` - work.

  Examples

      >>> x = np.array([3.0, 5.0, 2.0])
      >>> y = np.array([2.0, 1.0])
      >>> np.polydiv(x, y)
      (array([ 1.5 ,  1.75]), array([ 0.25]))
