The **`div()` function** in Ruby returns the result of the integer division of two numbers, e.g., dividend/divisor.

Figure 1 shows the visual representation of the `div()` function.

# Syntax
```ruby
dividend.div(divisor)
```
# Parameter
This function requires a divisor as a parameter.
> If the divisor is `zero`, then this function throws `ZeroDivisionError`.

# Return value
This function does the `integer division` of the two numbers and returns its result, e.g., dividend/divisor.
> If the result is floating-point, then this function *rounds down* or takes the `floor` of the result and gives the integer value.

# Example
The following example shows how to use the `div()` function in Ruby.

#both positive numbers
print "(15).div(4) : ",(15).div(4), "\n"

#negative dividend
print "(-15).div(6): ",(-15).div(6), "\n"

#zero dividend
print "(0).div(12): ",(0).div(12), "\n"

#fractional numbers and both numbers negative
print "(-15.6).div(-6.7): ",(-15.6).div(-6.7), "\n"

What is div() in Ruby?

The div() function in Ruby performs integer division, returning the quotient and raising errors if dividing by zero.
