The D’Hondt method, designed in 1878 by Victor D’Hondt, Belgian lawyer and mathematician, is a highest averages method for allocating seats in party-list proportional representation. Taking the total number of seats to assign and the amounts of votes for the parties as input, it calculates the seat numbers for each party.

In the example below, 254.000 voters decide the distribution of 8 seats among 4 parties with 103.000, 73.000, 47.000, and 31.000 votes, respectively. We provide two alternative explanations for how the number of seats for each party are calculated with the D’Hondt method.
