Divide and join are opposites. Divide is to split a whole into parts or shares. Join is to connect two things directly, or to become a member of a group. Divide breaks one into several; join connects two into one, or adds a member.
One splits a whole into parts; the other links two into one. Divide, from Latin dividere 'to force apart', parcels one whole into parts or shares. Join, from jungere 'to yoke', connects two things directly or adds a person to a group. An estate is divided among the heirs; two lengths of pipe are joined into one. One makes several out of one; the other makes one out of two.
divide
To divide is to split a whole into parts — often equal ones, and often methodically: divide a cake into six, divide the class into groups, divide twelve by three. From the Latin dividere, 'to force apart'. It is the tidy, measured cousin of split. As a noun, a divide is a gap or rift between groups — the digital divide, a widening social divide. The word reaches into maths (dividend, divisor) and into the old strategy of divide and conquer.
join
To join is to connect two things directly, or to become part of a group — join two pipes end to end, join a club, join hands. From the Latin iungere, 'to yoke'. At its simplest it makes one continuous thing out of two: where two roads meet, they can be joined into a single route. With people it means to enter or take up with — you join a team, join the queue, join forces. Unlike things that merge into one body, joined parts keep their own ends; they are linked, not dissolved.

Ask whether one is split or two are linked. Divide cuts one whole into measured parts that ease apart — a pie into even wedges. Join connects two things directly into one run — a fresh link closing two chains. If one thing is parcelled into parts, that is divide; if two things are connected, that is join.

Divide splits a whole into parts and is both verb and noun (a cultural divide); join connects two things or adds a member. Their human senses are opposite too: a question that divides people sets them apart, while joining a group brings a person in. One breaks one into many; the other links two into one.
