Try this:

t = 5.9
interval = 2.0

while t < 6.1:
    print (t, interval, t % interval)
    t+=0.1

Then you see what actually gets divided.... 
I'm not sure what you actually try to do, but AFAIK modulo is mathematically
only properly defined on integers - so you should stick to them. If you
need fractions, it might be sufficient to use fixed-point arithmetics by
simply multiplying by 10 ar 100.
