Aliquot Part.

Chambers's Encyclopaedia, Volume 1: A to Beaufort, p. 164

Aliquot Part. One quantity or number is said to be an aliquot part of another, when it is contained in this other an exact number of times without remainder. Thus 2, 2½, 4, and 5 are aliquot parts of 20, being contained in it 10, 8, 5, and 4 times respectively. The consideration of aliquot parts is of great importance in the arithmetical rule of Practice.
