The percentages are rounded down to give an integer. For example, 2/3 becomes 66%. - N. J. A. Sloane, Nov 17 2015
Eric Angelini asks "Does the sequence enter some kind of loop at some point?"
Comment from Jack Brennen, Nov 18 2015: I wrote a Python program to explore the sequence and computed over 10^7 terms without the sequence entering a loop. It exhibits some short term looping, but the loops don't last long.

EXAMPLE
The third digit in the string of terms 1005066025... is 0. When we reach that digit we have seen one 1 and two 0's, so 0 has appeared 2/3 = 66% of the time, and therefore a(3)=66. - N. J. A. Sloane, Nov 17 2015
