the only math operation that politely warns you before destroying everything: never by zero.
means The act of splitting something into parts, or the arithmetic operation of finding how many times one number fits into another — and, by extension, a separation between people, a section of an organization, or a boundary line.
from From Latin 'divisio,' the noun of 'dividere,' 'to force apart, separate' — built from 'dis-' ('apart') plus a root meaning roughly 'to separate, set off' (a cousin of 'widow' and 'individual,' the latter literally meaning 'not divisible'). It entered English through Old French 'division' in the medieval period, carrying both the cold math sense and the human one — the same word that splits numbers also splits nations and friendships.
