DIV

Syntax:
DIV

Integer division. Discards from the division result any fractional part
to the right of the decimal point.

If either operand has a noninteger type, the operands are converted to
DECIMAL and divided using DECIMAL arithmetic before converting the
result to BIGINT. If the result exceeds BIGINT range, an error occurs.
