On red step we multiply 6 by 4 to obtan 24, and subtract with 26, the solution is 2
O green step we add a comma to 4 do add a zero on the last solution (2), now the number is 20 and multiply 6 by 3 to obtan 18 and the solution is 2
As we can see the number two will be repeated forever since 20 divided by 6 is not exact, then the 3 will repeat infinitely
