The given total number of seats (23 in the applet) is to be apportioned between several (3 at the ouset) states proportionally to their populations. To accomplish that task according to Adams,

  1. Compute the divisor D = (Total population)/(Number of seats)
  2. Increase D by an amount d such that when state allocations {(State population)/(D + d)} are rounded upward, they add up to the exact number of seats.

(One of the applets at this site combines Adams' and four additional methods of apportionment under a single umbrella.)
