It seems to work for all of the convergents of pi, starting with the one I mentioned above. Most everyone knows 3 and 22/7 as the first two convergents. You can get the numerators and denominators of the first 26 or so from https://oeis.org/A002485 and https://oeis.org/A002486.
Nominal Animal:
If it matters any,  8958937768937 ÷ 2851718461558  has the same value as  π  in IEEE-754 Binary64 format: 0 10000000000 (1)1001001000011111101101010100010001000010110100011000.
