 Uses polynomial long division algorithm. Returns `(q, r)` where `q` is the quotient and `r`
 is the remainder such that `a(x) = b(x) * q(x) + r(x)` and `degree(r) < degree(b)`.

+fn degree(c []f64) int
+```
+
+This function returns the degree of the given polynomial.
+The polynomial is represented by the array `c`:
+
+```console
+P(x) = c[0] + c[1] x + c[2] x^2 + ... + c[n] x^n
+```
+
+The function returns the index of the highest non-zero term.
