If 0 times 0 is 0. But we know like 5 divided 10 is equal to 5 times 1/10. So 0 times 0 is 0 times 0/1 is 0 divided 1/0, buy 1/0 is 1 divided by 0. so then 1 / 0 is bad. So why?
Why is 1/0 undefined?
Division is the inverse of multiplication, therefore,
we know that 6/2 = 3 because 2 x 3 = 6
and that 18/3 = 6 because 3 x 6 = 18.
Now, if we try 1/0:
1/0 = ? if we can find a number to replace the question mark that solves this: 0 x ? = 1.
But there is no number we can use; no number multiplied by 0 will give us an answer of 1.
We get the same problem if we try 7/0 or -2/0 or 147/0 etc. [No number works.]
[Dividing 0 by 0 gives us a different problem; all numbers work.
We could argue that 0/0 = 1 because 0 x 1 = 0;
but then, by the same argument: 0/0 = 0 because 0 x 0 = 0
and 0/0 = 27 because 0 x 27 = 0
and 0/0 = -2 because 0 x -2 = 0.
So 0/0 is undefined because it has no single answer; every number works.]

I'm not sure if I entirely understand your question, but what it comes down to is that division is spliting a certian number of something into a certain amount of groups, and saying how much of that object is left in each group. Because you can not put objects in 0 or no groups, then you can also not divide by 0.
