write a function to receive a whole number and return true if the digits are in ascending order from right to left do not use string

public static bool AscendingDigits(int n)
    {
        // 12345
        // 12345
        int prev = int.MinValue;
        while (n != 0)
        {
            int remainder = n % 10;
            if (prev <= remainder)
            {
                prev = remainder;
                n = n / 10;
            }
            else
            {
                return false;
            }
        }

        return true;
    }
