Separate digits from integer (without string functions)

I have an integer with only two digits, let's say n = 52, i want to be able to separate these two digits, like 5 and 2.

Left Digit:

    int left = (n / 10);

This gives me left = 5 for n = 52.

Right Digit:

    int right = (int)(((n / 10f) - (n / 10)) * 10)

Error

The left digit is always true, but the right digits are sometimes right and sometimes wrong, and here are the test cases:

 1. 29, 48 , 10 , 50 : Correct 
 2. 52 : Wrong, gives 5 , 1
 3. 99 : Wrong, gives 9 , 8
 4. 26 : Wrong, gives 2 , 5

int n = 52 ;

Solution 1 : 

int left =int.Parse( n.toString().Substring(0,1)) ;
int right =int.Parse( n.toString().Substring(1,1)) ;

Solution 2 : 

int left = n / 10 ; 
int right = n % 10 ;
