If a remainder is obtained when dividing by the factor,
then the unit adds the remainders together. As soon as
this sum reaches or exceeds "1", the pump executes an
additional stroke. Therefore on average during the
metering operation, the resultant number of strokes pre‐
cisely matches the factor.
