I would stay with the 74193, except I would use two of them in cascade. Also use two of the 74LS47 decoders.
You can preload the 24 in, count down and when the output goes to 00 it will reload the 24.
The CD40110 is decade counter, but as far as I could see there is no way to preset the counter to any number.
