So taking your suggestion to use a quadratic number field, I get rid of syntax errors at last. But I guess the problem is too difficult as no answer comes back in a few minutes. I let Mathematica run a similar problem for 36 hours with no reply; but I don't understand why it's too difficult. Seems like it should be 16 polynomial quasi-divisions. I guess the coefficient expressions must blow up. But even if they have thousands of terms, polynomial division is quadratic so should happen in a few seconds.
