Getting a value of 0 when dividing 2 lengths in C #

I am trying to separate the values ​​of DriveInfo.AvailableFreeSpace and DriveInfo.TotalSize in order to try to get a percentage of it for use in the progress bar.

I need the final value to be int, since progressbar.value requires that int and the above methods return a long one.

I have this meaning:

164660715520 --- AvailableFreeSpace

256058060800 --- TotalSize

When I try to set the value of progressbar.value using this method, I also get the error message:

progressBar1.Value = (integer) (dInfo.AvailableFreeSpace / dInfo.TotalSize) * 100;

When I use this code to try to get the value, it just returns 0.

label10.Text =  (((int)dInfo.AvailableFreeSpace/dInfo.TotalSize)*100).ToString();

I even tried this and it does not work:

label10.Text = ((dInfo.AvailableFreeSpace/dInfo.TotalSize)*100).ToString();

, , , , , 0.

- long int?

. , 3/5 0. . :

label10.Text =  (((int)((double)dInfo.AvailableFreeSpace/dInfo.TotalSize)*100)).ToString();

label10.Text = ((100*dInfo.AvailableFreeSpace/dInfo.TotalSize)).ToString();

( 64).

long total = 256058060800L;
long avail = 164660715520L;
var pct = (100*avail/total).ToString();
Console.WriteLine("{0}", pct); // 64

double someVariable = (double) longVariable1/(double) longVariable2;

    {

        <strong>double t = (100 * (double)e.CurrentProgress / (double)e.MaximumProgress);</strong>
        if (t < 0)
            return;
        int c = (int)t;
        progressBar.Value = c;

        var sigRatio = (time2 / time1);
