How to Divide Massive Numbers with big.Int in Go?

Go: Dividing Massive Numbers (big.Int)

When working with massive numbers represented by the big.Int type in Go, division can be performed using the Div() method. This method accepts two big.Int variables and returns a new big.Int object containing the result of the division.

Consider the following example, where two big.Int variables, first and second, are initialized with factorials of 50 and 18, respectively:

<code class="go">first := new(big.Int).MulRange(1, 50)
second := new(big.Int).MulRange(1, 18)</code>

To divide first by second, you can use the Div() method:

<code class="go">dv := new(big.Int).Div(first, second)</code>

The resulting dv variable will contain the result of the division as an integer. You can print the result using the String() method to convert the big.Int to a string:

<code class="go">fmt.Printf("Division result: %s \n", dv.String())</code>

Running this code will produce the following output:

Division result: 4750440164794325701367714688167999176704000000000

This demonstrates how to perform integer division on massive numbers using the Div() method in Go's big package.
