All odd numbers are divisible by 2.
You just get a decimal in the quotient.

That’s not what divisible means

All odd numbers are divisible by 2 if you’re work modulo a prime.

It is, just not in mathematics.

what non-mathematical meaning are we talking about here?

Divisible in maths leaves no remainder or is only whole numbers. In the real world everything is divisible by 2 as it doesn’t have the caveat of whole numbers.

I think what they mean is still a mathematical meaning, just a separate definition of ‘divisible’ not limited to integers. The term is usually used for the set of integers, but really you could define it on any set.
“For x,y in S, x is called divisible by y if and only if x/y lies in S.” could be such a definition. Obviously you also need a definition of “/”, which is usually x/y=a <=> a*y=x with any operation *. This usually involves an algebraic Ring.

I believe the correct term is evenly divisible.
