# dividingFullWidth(_:)

Returns a tuple containing the quotient and remainder of dividing the given value by this value.

## Declaration

```swift
func dividingFullWidth(_ dividend: (high: Int64, low: Int64.Magnitude)) -> (quotient: Int64, remainder: Int64)
```

## Parameters

- `dividend`: A tuple containing the high and low parts of a double-width integer. The high component of the value carries the sign, if the type is signed.

## Return Value

Return Value A tuple containing the quotient and remainder of dividend divided by this value.

## Discussion

Discussion The resulting quotient must be representable within the bounds of the type. If the quotient of dividing dividend by this value is too large to represent in the type, a runtime error will occur.
