Usage

What is division? Division is the act of dividing, or separating, a whole into pieces, as in Mom made a chart that shows the division of chores is fair. A division is a piece of a whole, often with all divisions being equal in size. A division is also something used as a dividing line or mark between areas, such as a line of chalk on the sidewalk. Division can also be used figuratively to refer to a separation caused by a difference of opinion or disagreement, as in The division in our family was caused by a fight over whose macaroni and cheese was better. In arithmetic, division is the process that involves determining how many times one number is contained in another. For example, if we wanted to know how many times 2 is contained in 8, we would use division to find out, dividing 8 into groups of 2. Example: All questions related to funding and accounts should be sent to the accounting division.

Synonym Usage

Division, partition suggest dividing into parts. Division usually means marking off or separating a whole into parts. Partition often adds the idea of allotting or assigning parts following division: partition of an estate, of a country.

Etymology

Origin of division

First recorded in 1325–75; Middle English devisioun, divisioun, from Anglo-French, from Latin dīvīsiōn-, stem of dīvīsiō, from dīvīs(us) “divided” ( see divisible) + -iō -ion

Explanation

Division is breaking something down into parts, splitting it up. When you have division of labor, everybody does her part. Division is a noun. It refers to taking a hunk — of pie, clothes, numbers, people — and splitting it into smaller bits. A division in the military sense is a group large enough to go to battle. Blame British mathematician John Pell for the long division you learned in math class (but proceeded to forget once you discovered the calculator). Any way you slice it, division is the process of separating something into smaller parts.
