77078254 divided by 556 
We want to divide 77078254 by 556.

Advancing to step 1:
When dividing 7 by 556, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 556

On to step 2:
When dividing 77 by 556, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 556

Going ahead to step 3:
556 can be fit into 770 1 times, resulting in a remainder of 214.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 214 after subtracting 556 from 770.
Append the next digit (7) from the dividend to 214 and continue with: 2147 / 556

Let's proceed to step 4:
The number 556 fits into 2147 3 times, leaving a remainder of 479.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1668 from 2147 to get 479.
Take the next digit (8) from the dividend and append it to 479, then repeat: 4798 / 556

Going ahead to step 5:
556 can be fit into 4798 8 times, resulting in a remainder of 350.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Subtracting 4448 from 4798 leaves us with 350.
Take the next digit (2) from the dividend and append it to 350, then repeat: 3502 / 556

On to step 6:
556 goes into 3502 6 times with a remainder of 166.
Use 6 as the next digit of our solution. 
Result so far: 1386.0
If we subtract 3336 from 3502, we get 166.
Take the next digit (5) from the dividend and append it to 166, then repeat: 1665 / 556

Let's proceed to step 7:
556 can be fit into 1665 2 times, resulting in a remainder of 553.
Write down 2 as next digit of the result. 
Result so far: 13862.0
Subtract 1112 from 1665 to get 553.
Bring next digit (4) of the dividend behind the 553 and repeat the process: 5534 / 556

Advancing to step 8:
If we divide 5534 by 556, we get 9 and a remainder of 530.
Record the quotient 9 as the next digit in the result. 
Result so far: 138629.0
If we subtract 5004 from 5534, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 9:
556 can be fit into 5300 9 times, resulting in a remainder of 296.
Record the quotient 9 as the next digit in the result. 
Result so far: 138629.9
If we take 5004 away from 5300, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 10:
If we divide 2960 by 556, we get 5 and a remainder of 180.
Use 5 as the next digit of our solution. 
Result so far: 138629.95
The remainder is 180 after subtracting 2780 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
556 goes into 1800 3 times with a remainder of 132.
Put 3 as the next digit of the answer. 
Result so far: 138629.953
If we take 1668 away from 1800, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 12:
556 can be fit into 1320 2 times, resulting in a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 138629.9532
Subtract 1112 from 1320 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 13:
The number 556 fits into 2080 3 times, leaving a remainder of 412.
Put 3 as the next digit of the answer. 
Result so far: 138629.95323
If we take 1668 away from 2080, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 14:
If we divide 4120 by 556, we get 7 and a remainder of 228.
Use 7 as the next digit of our solution. 
Result so far: 138629.953237
The remainder is 228 after subtracting 3892 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 15:
556 can be fit into 2280 4 times, resulting in a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 138629.9532374
If we subtract 2224 from 2280, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 16:
If we divide 560 by 556, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 138629.95323741
If we subtract 556 from 560, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 138629.95323741 and a remainder of 4e-09.
