The problem with this 300 hZ solution is that when dividing by 5 the output waveform becomes easily a pulse instead of a 50% duty cycle square wave. That kind of signal is not easy to filter.
Dividing the frequency using harmonics would yield better result but the circuit would also become more complex. Esko, sorry, but I don't have the foggiest idea what you mean! There's no need for any filtering. The clock chips need periodically arriving edges at the clock input. The waveform, in particular the duty cycle doesn't play any role.
