Explanation

The least number to be added to the numbers to make them divisible by 9 is equal to the difference of the least multiple of 9 greater than the sum of the digits and sum of the digits. Sum of the digits = 15. Nearest multiple of 9 greater than the sum of the digits = 18. Hence, 3 has to be added. If we add 3 to 51234, we get 51237, which is fully divisible by 9.
