Here is an example. 2.4576 reference. S1 is a switch to select what output frequency. Look at the output frequency; there is a divide by 2 between for each pin.
In side the 4060 is a oscillator (top left) then a long line of divide by 2. Unfortunately not all frequencies are brought out. So you might think about the CD4040 and CD4020 which does have all the frequencies come out but does not have the oscillator.
**broken link removed**
The CD4060 has a brother (75HC4060) which works at 5 volts and is much faster.
----edited----
That circuit does divide by 2, divide by 2 ........ = 2,4,8,16,32,64,128,256,512,.....
There is another one that divides by 2,3,4,5,6,7,8,9,10 only.
