Write a method that counts how many times the digit 'targetDigit' appears within the positive integer parameter 'origNum'. The parameter 'targetDigit' will be a single non-negative integer. The parameter 'origNum' could be any positive integer. For example, if 'origNum' is 712114 and 'targetDigit' is 1, this method should return 3 since the digit 1 appears three times in the number 712114. Please note that you are NOT allowed to use ANY strings in solving this problem. Hint: Don't forget about the 'div' and 'mod' operators: / and % as these will be very helpful.
