Answer: 139
Explanation:
first, 4 can go into 5 once so you would put one down --> 5-5= 1
bring down the one and then put down the 5 from the tens place
4 can go into 15 three times which would be 15-12 = 3
so at the top, you would have 13 so far
then with the 3 left bring down the 6 from the hundreds place from the 556
lastly, since 4 can go into 36 nine times you would put 9 down next to 13 on the top which would make it 139
(Sorry if it doesn't make that much sense)
