The number 4 wins 71.7% of the first 100 million races (occurs most often in 71.7% of the races). It is also the leader after 100 million digits with a comfortable lead (10,003,863 occurrences compared to 10,002,475 occurrences of the 1 that was winning 15.9% of the first 100 million races). All numbers except the 6 were in the lead at some time. Number 6 was almost in the lead after 48,500 digits, only two occurrences short of the 1 at that time. In the first 100,000,000 digits of Pi the number 6 appears about 4450 times less than the current leader 4. But as the next comment shows the 6 finally takes the lead after 990,213,634 digits. - Ruediger Jehn, Jan 27 2021
Position at which a number (0 to 9) is leader for the first time: 174999, 4, 187, 1, 274, 11, 990213634, 320741, 108, 59 (see A342325). - Kester Habermann, Jan 27 2021

			The decimal expansion of Pi = 3.1415926535... starts with 3 (see A000796) hence the first leader in the race of digits is 3, so a(1) = 3. After 4 stages the new leader is 1 because the number 1 appears twice and the earlier leader appears once, so a(2) = 1. After 11 stages the new leader is 5 because the number 5 appears three times and the earlier leader appears twice, so a(3) = 5.

			The decimal expansion of e = 2.7182818284590452353602... starts with 2 (see A001113) hence the first leader in the race of digits is 2, so a(1) = 2. After 8 stages the new leader is 8 because the number 8 appears three times and the earlier leader appears twice, so a(2) = 8. After 23 stages the new leader is 2 because the number 2 appears five times and the earlier leader appears four times, so a(3) = 2.

This is A280811 with repeats removed. - Bobby Jacobs, Jan 12 2017

			The decimal expansion of gamma = 0.5772156649015... starts with 0 hence the first leader in the race of digits is 0, so a(1) = 0.
After four stages the new leader is 7 because the number 7 appears twice and the earlier leader appears once, so a(2) = 7.
After 14 stages the new leader is 5 because the number 5 appears three times and the earlier leader appears twice, so a(3) = 5.
