According to the equation $E = n \cdot h \cdot \nu$ (energy = number of photons times Planck's constant times the frequency), if you divide the energy by Planck's constant, you should get photons per second.

$\frac{E}{h} = n \cdot \nu$ $\to$ the term $n \cdot \nu$ should have units of photons/second.
