How Can I Divide Extremely Large Numbers in Go Using `big.Int`?

Dividing Massive Numbers in Go Using Big Integers

The problem of dividing extremely large numbers in Go arises when dealing with values that surpass the capacity of standard integer types. In this instance, the big.Int type from the "math/big" package offers a solution.

How to Divide Massive Numbers with big.Int

To divide massive numbers using big.Int, follow these steps:

<code class="go">package main

import (
    "fmt"
    "math/big"
)

func main() {
    // Initialize
    first := new(big.Int).MulRange(1, 50)
    second := new(big.Int).MulRange(1, 18)
    
    // Divide
    dv := new(big.Int).Div(first, second)
    
    // Print
    fmt.Printf("First: %s \n", first.String())
    fmt.Printf("Second: %s \n", second.String())
    fmt.Printf("Division result: %s \n", dv.String())
}</code>

Explanation:

1. Import the "math/big" package.
2. Initialize two big.Int variables (first and second) with the given numbers using MulRange, which calculates the factorial for a range of integers.
3. Use the Div method of big.Int to divide first by second, storing the result in the dv variable.
4. Print the original numbers and the division result using the String method, which converts big.Int values to strings.

Example Output:

First: 30414093201713378043612608166064768844377641568960512000000000000
Second: 6402373705728000
Division result: 4750440164794325701367714688167999176704000000000
