Why is the division of zero by itself not equal to one,since it is conventional that any number divided by itself is equal to one?,or maybe is zero not a number?

Dividing by zero is not defined. You can pretend it is defined and get nonsense results if you like. Zero is a number, yes. A lot of people are confused about this, you are not alone. Some people make up stuff about this problem. PF discusses mainstream Math, like you find in basic school text books, not personal theories.

We get this question frequently.

Because zero isn't part of the multiplicative group. The question does not exist. It's as if we asked why we can't breath on the moon.
