Anything you like, except zero, that's forbidden.
Usually when you ask "what can something be divided by", the implication is that you mean that both the divisor and the quotient should be integers and that there should be no remainder. In this case, the dividend is already not an integer, so there are no all-integer solutions and the question is essentially meaningless.
