TITLE: Formal symbol for the integer division operation
QUESTION [12 upvotes]: The integer division is a common and useful operation in Computer Science. It comes up in many domains, as in the manipulation of matrices and grids.
Is there any formal symbol for this operation? Or at least a widely recognisable symbol that can be easily differentiated from the standard division (i.e. inverse of multiplication)?

REPLY [2 votes]: I often use $\text{div}$, which is complementary with $\text{mod}$.
There are many alternatives (some used in programming languages) such as $/,//,\backslash,\div,\%$ but these don't go without saying.
Also $\left\lfloor\dfrac\cdot\cdot\right\rfloor$.
