If this is just for threading then you could run in counter mode. That would effectively divide the pulse rate by 4. If you still have problems then a simple binary counter such as a 74HCT93 can be used to divide one channel (counter mode only uses one channel) by 2,4,8 or whatever. 74HC series logic chips only cost a few pence.
If you want I can send you a circuit diagram of how to connect up a 74HCT93. It is dead simple and can even be made by simply soldering a few wires directly to the chip.
