# DIV function
<a name="DIV"></a>

The DIV operator returns the integral part of the division of dividend by divisor. 

## Syntax
<a name="DIV-syntax"></a>

```

```

## Arguments
<a name="DIV-arguments"></a>

 *dividend*   
An expression that evaluates to a numeric or interval.

*divisor*  
A matching interval type if `dividend` is an interval, a numeric otherwise.

## Return type

`BIGINT`

## Examples

The following example selects two columns from the squirrels table: the `id` column, which contains the unique identifier for each squirrel, and a `calculated` column, `age div 2`, which represents the integer division of the age column by 2. The `age div 2` calculation performs integer division on the `age` column, effectively rounding down the age to the nearest even integer. For example, if the `age` column contains values like 3, 5, 7, and 10, the `age div 2` column would contain the values 1, 2, 3, and 5, respectively. 

```
SELECT id, age div 2 FROM squirrels
```

This query can be useful in scenarios where you need to group or analyze data based on age ranges, and you want to simplify the age values by rounding them down to the nearest even integer. The resulting output would provide the `id` and the age divided by 2 for each squirrel in the `squirrels` table.
