So when you divide the RHS by N to get the average velocity, you now have the velocity of ONE typical molecule.

F is much too big for that. It was the force for ALL the molecules combined. So we have to divide that also by N.

Now ##\frac{F}{N}## = k ( average squared velocity of one molecule )

As you said, it is mathematically required that you divide both sides of an equation by the same thing.

It is also what averages are about.

Say F = the total number of chocolates in N boxes

Then ##\frac{F}{N}## = ##\frac{the\ total\ number\ of\ chocolates\ in\ N\ boxes}{N}## = the average number of chocolates in ONE box
