Zero is [technically] not a real number?
0/0 is not 1, it's indeterminate because 0 technically isnt a real number, it's more of a lack of number.
The concept of zero was problematic long after natural numbers were codified.
"How can nothing be something?" people would sagely ask.
But multiplication had its identity element [unity] and addition needed one as well.
Here's how Wikipedia puts it:
Zero (0) is the least non-negative integer.
The natural number following zero is one and no natural number precedes zero.
Zero may or may not be considered a natural number,
but it is a whole number
and hence a rational number
and a real number
(as well as an algebraic number
and a complex number).
That's a fairly impressive set of credentials.
So, yes, Virginia, there is a zero, and it's not technically disenfranchised.
Think of the score of a baseball game before the first pitch. Technically not a real score?
Think of the temperature [Celsius] of ice water. Technically not a real temperature?
Think of the number of ways that bonanova is perfect. He's technically not imperfect? [I can call several credible witnesses. ]
