Well, you can, if you just go right to one. Or if you count by tenths. Or by hundredths. It would be exhausting but you could do it. But if a whole number is infinitely divisible by adding more zeros to the right of the decimal, and it’s possible to keep writing zeros forever, then you could eventually find an increment so small that you would never reach one. Welcome to the Banach–Tarski Paradox.
