In some ways, the process for division is easier than for multiplication, as the fraction literally appears under the hairline, with the answer under the index. Because both indices of the C scale wrap around to represent the same place, there will always be at least one index that is on scale, and therefore will never need a change of index. | In some ways, the process for division is easier than for multiplication, as the fraction literally appears under the hairline, with the answer under the index.
