I would say that anything can divide into infinity infinitely, so the answer is infinity.
Scratchin those melons.

There is infinity, and then there is infinity.
Now, infinitesimal. Infinitesimal is to small, what infinity is to big. If you show me something infinitesimal, I'll cut it in half and give you something even more infinitesimal If that were not the case, we wouldn't call it infinitesimal, we would call it atomos.
Something on the order of infinitesimal is on the order of 1/infinity (well, any number, real or imaginery, divided by infinity)
So, I put it to you that an infinite quantity of stars, from each an infinitessimal number of photons, would not amount to a whole hill of beans.

Amazingly enough, I was thinking about that one only a few days ago (spooky!). A teacher threw that one at me at school, and I didn't really ponder it.
The logic is "if the universe is infinite, then travelling in any one direction you will eventually meet a star. Therefore the sky should be white".
However, it fails to take into account one very simple principle:
1) The "inverse square law", by which the intensity of the light reaching the observer diminishes over relatively short distances (short, compared to infinity at least )
Sure, you would get interference patterns from all the light sources overlapping, but these would be so faint your eyes would be unlikely to register them
Jim, I would be interested to hear why you don't agree with the Big Bang theory: are you more a follower of "steady state", or is there some other camp to which you subscribe? True, they are all merely theories, but the Big Bang is so convenient from the quantum level up!
Although, one could postulate the Big Bang theory is so popular because it isn't too far from our ancestors' beliefs in genesis!
