A quick solution to check if a number is divisible by 29 or not is to add 3 times of last digit to the remaining number and repeat this process until number comes 2 digit. The given number is divisible by 29 if the obtained two digit number is divisible by 29.

(39342+599316) ÷ 29

5 × 3 + 641 = 656

6 × 3 + 65 = 83

now 83 is not divisible by 29 hence

(39342+599316) is not divisible by 29
