    That's not a frequency divider. It's a lowpass filter.

    I think the circuit is an oscillator. The 100k pot must be turned down to less than 2k ohms to avoid oscillation if the frequency adjusting pots are set the same.

    The circuit is a Butterworth lowpass filter if the 100k pot is set to only 600 ohms.

    Use a 1k pot.
