I have done square waves with CMOS flip flops.  Quite simple, but they
are square waves.  The tricky part was the 1/3.  From it 1/6, 1/12,
1/9 etc are easily derived.  1/5, 1/7 would be extensions of the 1/3
idea.  I used this technique in my perfect fifth and octave generating
PLL circuit (which is on my FatMan website)
