you got two counters (count 0 ~ 2^22 and counter 0~255).

count outputs clkout at n/2 and n (not exactly right, should be n/2-1 and n-1 due to zero start value), it counts clocks

counter drives led output and is enabled when count is max

both counters can be free running as they are binary range(0~255,0~ 2^22-1) if you correct your range.
