There are chips (which are less expensive) which do frequency scaling for you.
Is there a special reason why this must be done in PIC (aside from learning
about the PIC, which is a very good reason)?

Assuming you are using a 16f84, there is an input to a counter on it which
allows you to count pulses as well.  You may want to look into this.

The jitter depends on your program.  If you can show us the program we might be
able to point it out.  Otherwise we can give general ideas, but nothing
specific.

Is the ratio input/ouput set, or are you trying to change it while it is
operating?  What is the ratio range (ie, 1:256 - 1:1)?  What is the highest
frequency you are likely to use?
