Apparently it did have some historical use, but I'm told (maybe hearsay?) that it was not used in primary education til more recently (my gen or later).
I read "÷" the same way I read "xʸ", as a representation for the operation with placeholders but not valid/reasonable as an operator itself.
Surely "/" has the same problem, and I'm certain my parents learned to use one or the other.
I don't recall being taught anything but fraction bar (vertical formatting) or long division. "/" was calculator/programming only.
Other oddities are grouping: instead of parenthesis, math teachers used to use curly and square brackets, to help prioritize operations. I remember a teacher being surprised that "computers only uses parenthesis".
I remember it, but I am old and from the UK where perhaps it was more common
÷ was used in primary school teaching (UK) before at least 1980. / is for C programmers.
