If I Continue sharing substance on in half. I reach ‘Molecules’ the smallest unit of substance. And if I keep divide Molecules in many time, molecules are divided into ‘atomic’. Also keep divide atomic in many time than it divided by ‘electron’, ‘proton’ and ‘neutron’ . Than put neutrons and protons into particle accelerator, it divided by ‘quark’.

like this pattern when I keep divide pizza to half,  after all we can’t see  slice of pizza. But if we have technology and we can cut it that we can’t see, we should divide pizza in our whole life.

Moreover, if we say ‘I ate something’s half’, it means it left another half.

So in my opinion, there is no end of divide pizza.
