Pushed an implementation for divide and remainder:


jshell> PolynomialDouble p = PolynomialDouble.valueOf(1, 1, 2);
p ==> (2.0*x^2 + x + 1.0)

jshell> PolynomialDouble q = PolynomialDouble.valueOf(1, 1, 0, 4);
q ==> (4.0*x^3 + x + 1.0)

jshell> p / q
$3 ==> 0.0

jshell> p % q
$4 ==> (2.0*x^2 + x + 1.0)

jshell> q / p
$5 ==> (2.0*x + -1.0)

jshell> q % p
$6 ==> 2.0
