It is a matter of measure. The interval's length is divided as \(\frac{1}{2} + \frac{1}{4} + \frac{1}{8} + \ldots = \sum_{n}\frac{1}{2^{n}}\). Each part is worth half as much as the previous one and thus the sum converges. Zeno is counting the number of intervals, ignoring that they are half the length of one another. It's the basis of convergent series, you can add infinitely many things together and still get a finite answer.
