No need. Because you're the one asserting that Peter would put him down with cumulative punches; I never once said that Ares would punch him.
So go on, how many? Because at this rate, Spidey tires himself out lol. If you say 'a lot', well, a million is a lot. Spiderman would die of exhaustion from throwing one million punches. Ares wins just by standing there.
