If you're talking about basic foxtrot as in dancing a basic quickstep, but more slowly (what we call "rhythm dancing in UK"), then Kevin is absolutely correct, and it works very well for social dancing.
If you try some more advanced foxtrot figures, such as feather step - reverse turn - feather finish, you will find the timing is Slow - Quick - Quick, with the slow occupying beats 1 and 2 and the two quicks each occupying 1 beat (making 3 and 4).
However, the beauty of foxtrot is that it can be very sophisticated in its rhythms, allowing the dancer some leeway to use his own musical interpretation, departing from the strict 2 beat slow and 1 beat quick structure. All this pleasure is ahead of you!!

I think that foxtrot is the dance that most
epitomizes ballroom dancing. It is a dance of
structure and elegance, and if not appreciated
as such, should probably be left alone.
American style is not very standardized and
is probably not taught the same in any two places. But, the basic step is usually
S S Q Q or S Q Q. English style actually has no
core basic, but is progressed around the floor
through various figure combinations that are
comprised of slows and quicks.
