Full wave rectify the sinewave input, extract the 8th Harmonic with a passive filter.
Drive the input of a divide by 5 circuit via a suitable impedance converter network.
Could even use a CMOS 74XX74 flipflop plus a few passive components as the divider.

The main requirement is perfect cycle count accuracy. This is for driving a 16 MHz microcontroller from a 10 MHz Rb/Cs/GPSDO. 10 MHz input is likely sine; 16 MHz output is 3v3 or 5v CMOS.
