Zero divided by any number, rational or irrational, would still be zero.

However, division by infinity (or negative infinity) is not a defined operation. Although we can state that for any number a,
a/ ∞ = 0 and a/- ∞ = 0
this is not an actual value of zero, but a limiting value for a number that approaches ∞ . You can see that the reverse multiplication operation,
∞ x 0 = a
is only true in the single case where a = 0.

In ordinary math, no matter what the divisor, division of infinity is not defined.
Similarly, division by zero is not defined. Nothing, not even zero, can be rationally divided by zero. So division of infinity by zero cannot have a result.

No. Zero multiplied or divided by anything is zero.
Infinity divided by any finite number is infinity. Here are the rules: 1. Infinity divided by a finite number is infinite (I / f = I); 2. Any finite number divided by infinity is a number infinitesimally larger than, but never equal to, zero (f / I = 1 / I); 3. Infinity divided by infinity is one (I / I = 1), or in fact any other positive number (I / I = and so on...); 4. Infinity multiplied by zero (no infinity) is zero (I * 0 = 0); 5. Infinity divided by a positive finite number is infinity (I / +f = I); 6. Infinity divided by a negative finite number is minus infinity (I / -f = -I); 7. Infinity divided by zero is not possible; 8. Infinity plus infinity is infinity (I + I = I); 9. Zero divided by infinity (nothing divided into infinity) equals zero (0 / I = 0); 10. Infinity plus a finite number is infinity (I + f = I); 11. Infinity minus a finite number is infinity (I - f = I); but 12. Infinity minus infinity, due to the nature of infinity, can be zero, infinity, or minus infinity (I - I = -I, 0, I).

When any number is divided by infinity, the result approaches zero but never actually reaches it. This is because infinity is not a specific number but rather a concept representing unboundedness. Mathematically, the limit of any finite number divided by infinity as infinity approaches infinity is zero.
