Probably right before the verb, by the conventional belief in a proper word order. But, I disagree with the idea - there is no "unusual emphasis" in "Gallia est omnis divisa in partes tres", and yet the verb is the second word. Then, look to the next sentence, "quarum unum incolunt Belgae".
That isn't to say that the final-position of the verb isn't more common, but rather that the idea that it is the "correct" non-emphatic word order seems flawed to me.
