clock division

Greetings everyone, I'm trying to divide the clock frequency by 2, 4, 8 for a (4x1 Multiplexer) in which the first input is the clock but the other three are the clock divided by the above numbers. Could anybody show me how to do it? I would be very grateful

Regards

    Your code currently does nothing for several reasons:

    1. You are only trying to initialise the variables - they are not changing dynamically

    2. You cannot divide a single bit by anything.

    I suggest using a counter somewhere.

    I also suggest you do not use the clock any any logic equation, or generate a clock from logic. Doing this is very bad practice - you need to generate clock enables instead.
