We're dividing 77381482 by 556 
Our goal is to divide 77381482 by 556.

Step 1:
7 divided by 556 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 556

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.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 556

Advancing to step 3:
When dividing 773 by 556, we get 1 with a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 556 away from 773, we end up with 217.
Take the next digit (8) from the dividend and append it to 217, then repeat: 2178 / 556

Moving on to step 4:
If we divide 2178 by 556, we get 3 and a remainder of 510.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 1668 from 2178 to get 510.
Take the next digit (1) from the dividend and append it to 510, then repeat: 5101 / 556

Moving on to step 5:
556 can be fit into 5101 9 times, resulting in a remainder of 97.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Subtracting 5004 from 5101 leaves us with 97.
Append the next digit (4) from the dividend to 97 and continue with: 974 / 556

Moving on to step 6:
If we divide 974 by 556, we get 1 and a remainder of 418.
Record the quotient 1 as the next digit in the result. 
Result so far: 1391.0
The remainder is 418 after subtracting 556 from 974.
Include the next digit (8) from the dividend after 418, then repeat: 4188 / 556

Moving on to step 7:
If we divide 4188 by 556, we get 7 and a remainder of 296.
Put 7 as the next digit of the answer. 
Result so far: 13917.0
Subtracting 3892 from 4188 leaves us with 296.
Bring next digit (2) of the dividend behind the 296 and repeat the process: 2962 / 556

On to step 8:
The number 556 fits into 2962 5 times, leaving a remainder of 182.
Use 5 as the next digit of our solution. 
Result so far: 139175.0
Deduct 2780 from 2962 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 9:
The number 556 fits into 1820 3 times, leaving a remainder of 152.
The number 3 becomes the next digit in our result. 
Result so far: 139175.3
The remainder is 152 after subtracting 1668 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 10:
If we divide 1520 by 556, we get 2 and a remainder of 408.
The next digit of our result is 2. 
Result so far: 139175.32
Deduct 1112 from 1520 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 11:
When dividing 4080 by 556, we get 7 with a remainder of 188.
Record the quotient 7 as the next digit in the result. 
Result so far: 139175.327
Deduct 3892 from 4080 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 12:
1880 divided by 556 is 3 with a remainder of 212.
Use 3 as the next digit of our solution. 
Result so far: 139175.3273
Subtract 1668 from 1880 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 13:
If we divide 2120 by 556, we get 3 and a remainder of 452.
Use 3 as the next digit of our solution. 
Result so far: 139175.32733
If we subtract 1668 from 2120, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final outcome is 139175.32733, with a leftover of 0.000452.
