Need help with CD4059A "Divide-By-N" Chip

I need help setting up this to an N factor of 1000. I am trying to lay this
chip out on a PCB. I have the manufacturer data sheets, but I don't
understand them.

Any help would be great.

Never used this IC before, but what i understand from the datasheets is that
the preset value contains the N-factor divided by the mode you use...

So, if you use mode 4 with N = 1000, the preset value equals 1000 / 4 = 250
remainder 0
which implicates that:
- Mode selection inputs (Ka->Kc) have to be: LHH (mode 4)
- Remainder inputs for mode 4 (J1 -> J2) have to be: LL (no remainder)
- Resultant inputs for mode 4 (J3 -> J16) have to be: LL LLHL LHLH LLLL
(BCD-notation of 250)

Sorry, Program jam inputs must apparantly be given in reverse order, except
for the MSB so:
- Resultant inputs for mode 4 (J3 -> J16) have to be: LL LLLL LHLH LLHL
