The smallest subset into which the number 0 fits is the set of all integers, commonly denoted as the set of integers \( \mathbb{Z} \), since 0 is an integer. Additionally, since 0 is also a whole number, it fits into the set of whole numbers and the set of real numbers as well. However, the most specific answer in terms of standard mathematical classifications is that 0 belongs to the set of integers.
