How to make a 20 LED chaser with 4017 ?
But only 1 led at a time and counting from 0 to 20.
 
The 4017 can do a 10 LED chaser on its own. You use daisy chain more than one 4017 together by connecting the last output of the 1st IC to feed the clock input of the 2nd.

So you mean like this, right?

But is not sequentially !
When A is clocking B is not doing it sequentially, meaning 1 after 1 (or one after another), but binary,
meaning when A is finishing a pass, it will increment B with 1 and then A will start another round.
It is counting 0123456789 in A then 11 in B. (since 10 was lit up until this time) then again 0123456789
in A then 12 in B (since 11 was lit up until this time) and so on.
All I want is an incremental and cursive 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
