You will need a clock shaper to convert the sine to a digital signal, and a series of dividers.
You can look at my page on clock shapers for ideas: http://www.ko4bb.com/Timing/ClockShaper.html If you look through the archives, I believe earlier this year there was a thread about the respective noise performance of various logic technologies, but I am sure someone can recommend the current best-in-class divider for low noise. For any but the most demanding applications, I am sure that standard CMOS decade counters in the AC, HC, ACT or HCT series would work fine, such as the 74ACT162.
