Ananlogue dividers??? Do you mean perhaps hetrodyne mixers?

Please place a schematic !

No, they're more like pulse accumulators with thresholds: after N pulses, the threshold is reached and it dumps the accumulator capacitor and pulses the output.

I've used this trick to get frequency division by 5 on a square wave,
using a multivibrator.

Also known as stairstep generators. Commonly used to step the base current, in such things as Tektronix transistor curve tracers, while the collector is being swept. Ira.
