using lpm_counter to divide a clock by any No

Why dont you want to go back to coding? Block diagrams have many disadvantages over code:

1. You cannot simulate a block diagram (it has to be converted to HDL first)

2. Block diagrams are not portable between vendors

3. Block diagrams dont work very well with version control.

Using a counter is possible to do anything - but I suggest not using the mod function - it implements a divider which may complete in a single clock and be very slow. And you should not generate a clock with logic anyway. It is much better practice to create a clock enable so that all logic uses the system clock, only enabled when required (every other clock, every third clock etc).
