/= (Division Assignment) (Transact-SQL)

[!INCLUDE sql-asdb-asdbmi-asa-pdw-fabricse-fabricdw]

Divides one number by another and sets a value to the result of the operation. For example, if a variable @x equals 34, then @x /= 2 takes the original value of @x, divides by 2 and sets @x to that new value (17).
