If lists of candidates are being voted on by constituencies, the number of seats obtained by individual lists in the constituency shall be determined by the quotient, which shall be calculated by dividing the total number of votes cast for all lists of candidates in the constituency by the number of members of the municipal council to be elected in the constituency. The number of votes for each list shall be divided by this quotient. Each list shall be allocated a number of seats equal to the number of times the quotient is included in the number of votes for the list.
