generating 40kHz signal on FPGA

Hi, I'm beggining to programm FPGA Cyclone II EP2C5T144C8N board. My question is how can I get a 40kHz signal output from 50MHz clock? (Pll isnt working) Really looking forward to reply:)

Well, lets see. 50 MHz is 50,000,000 Hz.

And 40 Khz is 40,000 Hz.

50,000,000 / 40,000 is 1250.

So how about a divide by 1250 counter?

That enough to get you going?
