As they say (at least in german): `tastes vary`.

If `a` and `b` are integer numbers, I consider

    int(math.floor(a / b))

to be considerably uglier than

    int(a / b)

Both are explicit, but use of a floating point function like floor in
a pure integer context is less than obvious. Besides, the quotient
operation might be part of a bigger expression -- even the use of a
single function call might reduce readability there.
