It has no answer and is undefined since infinity is not a number, but just a concept of something very big. You need actual numbers, or something that resolves to a real number, like a limiting series, to give an answer.  Sounds like you are in a very advanced math class!

It is 1, right? A number divided by itself will always be one, right?

Great question!

Going to offer a proof that the answer is not 1.

Assume Infinity / Infinity = 1

Next, we can say

Infinity + Infinity = Infinity  You could claim 2 X Infinity is the answer, that just equals Infinity.

So now you have

(Infinity + Infinity) / Infinity = 1

or

Infinity/Infinity + Infinity/Infinity = 1

If Infinity / Infinity = 1, you would get

1 + 1 = 1

2 = 1, which is obviously false,

so Infinity/Infinity cannot equal 1

I see your point, but infinity is a number, and a number divided by itself, is one, right? I'm not saying you are wrong, I'm just wondering.
Anything divided by itself is 1

It's 1 because any number divided by itself is one.

Infinity is infinite, or a really large number that is impossible to count to.

So, Infinity / Infinity would be infinity because infinity is infinite, so its forever counting, that is a trick question.
