convert int to double

I've tried working this several different ways and keep making things worse and worse. please help

Program.cs 
using System;

class Program
{

    // YOUR CODE HERE: Define a Divide method!
static double Divide(int dividend, int divisor)
{
    (double)dividend;
    (double)divisor;
    return (double)dividend/divisor;
}


    static void Main(string[] args)
    {

        // This should print "2.5".
        Console.WriteLine(Divide(5, 2));
        // This should print "3.3333333333..."
        // (Or a value close to that, since it can't be
        // infinitely precise.)
        Console.WriteLine(Divide(10, 3));
    }

}

Hey there so I know how terrible my code looks but I've been up all night and im just not getting this for some reason. I'm a bit stuck on the "Let's practice type conversion. Define a Divide method that takes two int values as parameters, and returns the result of dividing them as a double value. For example, Divide(5, 2) should return 2.5. (Normally, a method like this should probably take double parameters, but we want to practice converting values from int to double.)

You'll need to convert each of the int values to double before performing the division operation, so you don't lose the fractional portion of the result." problem.

You mostly have it, just remove the two lines before the return. The compiler message was trying to tell you that you can't have values by themselves as a statement (nor do you need them).
