n%10 means the modulus of 10, that is the remainder you get when you divide with 10. Here it is used to get each digit.

Example:

Say your number is n = 752.

n%10 = 2, n/10 = 75

So you add 2 to the sumDigits(75)

Now, n%10 = 75%10 = 5. This is the digit to be added and so on, till your n >= 10. When it is < 10, you have a single digit that you just need to return as it is, as that is only the sum of digits in that single-digit number n.
