There was a huge divide in London too. Places like Camden, Kensington and Barnet overwhelmingly voted remain. Other places like Havering, Barking and Dagenham and Bexley voted to leave. And some areas (like Newham) were extremely close as far as percentages go.
General rule seems to be that places with lots of university students or large businesses tended to vote remain and those with either deeply conservative populations or a lot of immigration tended to vote leave.

Doesn't think that is true. Lewisham, Lambeth and Tower Hamlets are some of the places with the most immigrants and remain won in all of these places by obscenely large margins.
Maybe votes were more along racial lines - White English (especially the older ones) voting to leave, but people with a more colourful Asian/Caribbean heritage voting to remain?
I don't think pretending there is a huge geographical divide is particularly helpful.
