# FHIRPath Operator: / (divide)
Divides the left operand by the right operand (supported for Integer, Decimal, and Quantity). The result of a division is always Decimal, even if the inputs are both Integer. For integer division, use the `div` operator.

If an attempt is made to divide by zero, the result is empty.

For division involving quantities, the resulting quantity will have an appropriate unit:

``` fhirpath
12 'cm2' / 3 'cm' // 4.0 'cm'
12 / 0 // empty ({ })
```
## Summary

- **Left Argument**: `Integer | Decimal | Quantity`
- **Right Argument**: `Integer | Decimal | Quantity`
- **Return Type**: `Decimal | Quantity`
- **Empty Input Result**: `empty`
- **Errors on Multiple Input**: `true`
## Description
Divides the left operand by the right operand. The result is always Decimal, even if inputs are Integer. Each operand must be a single element. Division by zero results in empty collection. For quantities, the resulting quantity will have an appropriate unit.
