A singularity popping out of the math is almost always an indication that something else is going on. According to general relativity, at the center of a black hole there might be some kind of "singularity" - but in reality what that means is GR is probably inadequate, when used alone, to describe the center of a BH. "Singularity" really means "your math broke and you need to fix it" by bringing in another theory that can fill in the gaps - or, rather, extending the current theory in a way that eliminates the division by zero.
