New round. After counting first and second-place votes, B4 and B5
exceed quota and tie for first place, at 193 votes each. We give one
seat to B4. Ballots of groups g, h, and i are marked as being worth
0.1556886 of their previous value. That leaves group
f = 0.3041666 x 120 ballots = 36.5 votes total for the group
g = 0.0473552 = 5.682624
h = 0.0473552 = 5.682624
i = 0.1556886 x 120 ballots = 18.682632 votes total for the group
j = 0.0473552 x 120 ballots = 5.682624 votes total for the group
which totals to 72.230504 votes total remaining for the voters of
party B. Add in the 400 of party A, ballots now total 472.23, new
Droop quota is 158. (Odd. Perhaps multiplying fractions raises issues
of precision? Or did I just make an error somewhere?)
At any rate, it's clear that the voters of party A will take the
remaining two seats. So in this example at least, the algorithm gives
the proper answer.

Postscript: Yes, I made an error. Group j is still at 0.3041666 so it
has 36.5 votes total for the group. Ballots now total 103.04788 for
party B, 400 for party A, new Droop quota is 168. That much error I
can accept from rounding.
The fact that party B has that many votes left after taking three
seats makes me wonder if perhaps a larger quota should be used.
Hare >= ideal quota >= Droop.
