how pure will the input signal be? if it's dirty and the dominant frequency doesn't stand out that much then you're entering FFT territory. if you want all frequencies downshifted then you can't do that on a squarewave output.

if your input frequency is moderately clean then you should consider a dumb solution like pic related.
