77016636 ÷ 556 
Our goal is to divide 77016636 by 556.

Let's proceed to step 1:
7 divided by 556 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 556

Moving on to step 2:
77 divided by 556 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 556

Let's proceed to step 3:
If we divide 770 by 556, we get 1 and a remainder of 214.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 556 away from 770, we end up with 214.
Include the next digit (1) from the dividend after 214, then repeat: 2141 / 556

Advancing to step 4:
The number 556 fits into 2141 3 times, leaving a remainder of 473.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 473 after subtracting 1668 from 2141.
Take the next digit (6) from the dividend and append it to 473, then repeat: 4736 / 556

Going ahead to step 5:
556 can be fit into 4736 8 times, resulting in a remainder of 288.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
If we subtract 4448 from 4736, we get 288.
Fetch the next digit (6) from the dividend, attach it to 288 and continue: 2886 / 556

Advancing to step 6:
The number 556 fits into 2886 5 times, leaving a remainder of 106.
Use 5 as the next digit of our solution. 
Result so far: 1385.0
If we subtract 2780 from 2886, we get 106.
Grab the next digit (3) from the dividend, add it to 106, then carry on: 1063 / 556

Step 7:
The number 556 fits into 1063 1 times, leaving a remainder of 507.
Use 1 as the next digit of our solution. 
Result so far: 13851.0
Subtracting 556 from 1063 leaves us with 507.
Append the next digit (6) from the dividend to 507 and continue with: 5076 / 556

Advancing to step 8:
When dividing 5076 by 556, we get 9 with a remainder of 72.
Write down 9 as next digit of the result. 
Result so far: 138519.0
Deduct 5004 from 5076 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
When dividing 720 by 556, we get 1 with a remainder of 164.
The number 1 becomes the next digit in our result. 
Result so far: 138519.1
Subtracting 556 from 720 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 10:
When dividing 1640 by 556, we get 2 with a remainder of 528.
The next digit of our result is 2. 
Result so far: 138519.12
Subtracting 1112 from 1640 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 11:
5280 divided by 556 is 9 with a remainder of 276.
Record the quotient 9 as the next digit in the result. 
Result so far: 138519.129
The remainder is 276 after subtracting 5004 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 12:
556 goes into 2760 4 times with a remainder of 536.
Put 4 as the next digit of the answer. 
Result so far: 138519.1294
Deduct 2224 from 2760 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 13:
556 can be fit into 5360 9 times, resulting in a remainder of 356.
The next digit of our result is 9. 
Result so far: 138519.12949
If we subtract 5004 from 5360, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 14:
556 can be fit into 3560 6 times, resulting in a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 138519.129496
The remainder is 224 after subtracting 3336 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 15:
556 can be fit into 2240 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 138519.1294964
Subtracting 2224 from 2240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 16:
556 goes into 160 0 times with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 138519.1294964
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 138519.1294964 with a remainder of 1.6e-07.
