Thank you all for the responses. But to clarify my original question,
is there anything wrong with the circuit below or not? Is the design
flawed or incorrectly implemented?

Thanks,

Lewis

And re-drew it as follows.

But ... it does not appear to work as described. The input is a 512 Hz
clock pulse. The output on pin 3 of the CD4051 is a slightly noisey
plain squarewave divided by 32 (16Hz). IOW no steps.

Can anyone point out a design fault in this circuit or other reason
why it might not work?
