c# - Get the seventh digit from an integer

I have a integer of 10 digits. I need to get the 7th digit of that integer.

I have found a mathematical solution to get the first digit of an integer.

var myDigit = 2345346792;

var firstDigit = Math.Abs(myDigit);
while (firstDigit >= 10)
{
     firstDigit /= 10;
}

How can I get the seventh digit from myDigit? I am trying to avoid casting to string and doing a substring. I would like to see the mathemathical version of getting the seventh digit.

Anyone?
