How do I redesign this code to avoid goto?

Question

Well, I have this problem because I started my journey with C# and I wrote a console calculator, but I used goto in it and I heard to not use it, but I have no clue what other instruction to use to make it work just how I want it to. I paste my code (it's not long) here, so maybe you can look at it and give me some tips. Thanks!

base:
        Console.WriteLine("First number");
        double first = double.Parse(Console.ReadLine());
        Console.WriteLine("Second number");
        double second = double.Parse(Console.ReadLine());

        Console.WriteLine("What operation do you want to perform? \n1 - addition \n2 - subtraction \n3 - multiplication \n4 - division");
        string choice = Console.ReadLine();
        if (choice == "1")
        {
            Console.WriteLine(first + second);
            Console.ReadLine();
        }
        if (choice == "2")
        {
            Console.WriteLine(first - second);
            Console.ReadLine();
        }
        if (choice == "3")
        {
            Console.WriteLine(first * second);
            Console.ReadLine();
        }

        else if (choice == "4" && second == 0)
        {             
            Console.WriteLine(" Do not divide by zero");                
        }
        if (choice == "4")
        {
            Console.WriteLine(first / second);
            Console.ReadLine();
        }

        Console.WriteLine("Next one? \n1 - Yes \n2 - No");
        string chc2 = Console.ReadLine();
        if (chc2 == "1")
        {
            goto base;
        }
        if  (chc2 == "2")
        {
            Console.WriteLine("Bye bye");
            Console.ReadKey();                

        }

Use loops. Here's one common way:

while (true) {
    // do some stuff
    Console.WriteLine("Next one? \n1 - Yes \n2 - No");
    string chc2 = Console.ReadLine();
    if (chc2 == "1")
    {
        continue; // means go back to the top of the loop
    }
    if  (chc2 == "2")
    {
        Console.WriteLine("Bye bye");
        Console.ReadKey();                
        break; // means break out of the loop
    }
}
