    I'm actually a student of Computer Engr working in various project and I'm about to embark on A 2 STAGE FREQUENCY DIVIDER>
    I've generate decided to the clock pulse from a 555 osscillator but I'm still confused on the technicality of the circuit diagram.
    Help from as many people would be so much appreciated. Thanks.

    555 timers in an astable mode can generate output frequencies of fractions of Hz to several hundred kHz. Since they use RC time constants, the output frequencies aren't particularly stable. They're fine for applications where the output frequency can vary several percent over time/temperature.

    If you're thinking of making something like a clock, you'll need a more accurate timebase; like a crystal oscillator.

    You can implement a two stage frequency divider with a pair of just about any logic family counters. How far down do you want to divide the frequency?
