The only problem with a 4017 is this:
One of the outputs must be HIGH.
It depends on what you actually want to do.
You need to be more specific.
Do you want a "run of 20?"

The most you can get from two 4017's is a "run of 18" as shown in the previous circuit.

... but you can cascade as many of them as you want to get the desired number of outputs ...
