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

  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).

## Syntax  
  
```syntaxsql  
expression /= expression  
```  
  
## Arguments
 *expression*  
 Is any valid [expression](../../t-sql/language-elements/expressions-transact-sql.md) of any one of the data types in the numeric category except the **bit** data type.  
  
## Result Types  
 Returns the data type of the argument with the higher precedence. For more information, see [Data Type Precedence (Transact-SQL)](../../t-sql/data-types/data-type-precedence-transact-sql.md).  
  
## Remarks  
 For more information, see [(Division) (Transact-SQL)](../../t-sql/language-elements/divide-transact-sql.md).  

## Examples  
The following example, sets a variable to 17. Then uses the `/=` operator to set the variable to half of it's original value.  
```sql  
DECLARE @myVariable DECIMAL(5,2);
SET @myVariable = 17.5;
SET @myVariable /= 2;
SELECT @myVariable AS ResultVariable;  
```
