Example

a(1)/a(2) = 2/1 = 2 and 2 is both the 1st digit of the division and S;
a(2)/a(3) = 1/6 = 0.1666... and 1 is both the 2nd digit of the division and S;
a(3)/a(4) = 6/9 = 0.6666... and 6 is both the 3rd digit of the division and S;
a(4)/a(5) = 9/17 = 0.5294... and 9 is both the 4th digit of the division and S;
a(5)/a(6) = 17/23 = 0.7391... and 1 is both the 5th digit of the division and S;
a(6)/a(7) = 23/18 = 1.27777... and 7 is both the 6th digit of the division and S;
etc.
