# %= (Modulus Assignment) (Transact-SQL)
[!INCLUDE [sql-asdb-asdbmi-asa-pdw](../../includes/applies-to-version/sql-asdb-asdbmi-asa-pdw.md)]

  Divides one number by another and sets a value to the result of the operation. For example, if a variable @x equals 38, then @x %= 5 takes the original value of @x, divides by 5 and sets @x to the remainder of that division (3).
