66788787 divided by 556 
We want to divide 66788787 by 556.

Let's proceed to step 1:
The number 556 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 556

Advancing to step 2:
When dividing 66 by 556, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 556

Moving on to step 3:
556 goes into 667 1 times with a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 556 away from 667, we end up with 111.
Fetch the next digit (8) from the dividend, attach it to 111 and continue: 1118 / 556

On to step 4:
1118 divided by 556 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 6 after subtracting 1112 from 1118.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 556

Going ahead to step 5:
When dividing 68 by 556, we get 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we subtract 0 from 68, we get 68.
Append the next digit (7) from the dividend to 68 and continue with: 687 / 556

Step 6:
When dividing 687 by 556, we get 1 with a remainder of 131.
The number 1 becomes the next digit in our result. 
Result so far: 1201.0
Subtract 556 from 687 to get 131.
Grab the next digit (8) from the dividend, add it to 131, then carry on: 1318 / 556

Step 7:
When dividing 1318 by 556, we get 2 with a remainder of 206.
Write down 2 as next digit of the result. 
Result so far: 12012.0
Deduct 1112 from 1318 and we're left with 206.
Grab the next digit (7) from the dividend, add it to 206, then carry on: 2067 / 556

Let's proceed to step 8:
556 can be fit into 2067 3 times, resulting in a remainder of 399.
The number 3 becomes the next digit in our result. 
Result so far: 120123.0
If we take 1668 away from 2067, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 9:
If we divide 3990 by 556, we get 7 and a remainder of 98.
Record the quotient 7 as the next digit in the result. 
Result so far: 120123.7
If we subtract 3892 from 3990, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
When dividing 980 by 556, we get 1 with a remainder of 424.
The number 1 becomes the next digit in our result. 
Result so far: 120123.71
If we subtract 556 from 980, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 11:
556 can be fit into 4240 7 times, resulting in a remainder of 348.
Record the quotient 7 as the next digit in the result. 
Result so far: 120123.717
Subtracting 3892 from 4240 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 12:
The number 556 fits into 3480 6 times, leaving a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 120123.7176
If we take 3336 away from 3480, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 13:
If we divide 1440 by 556, we get 2 and a remainder of 328.
Write down 2 as next digit of the result. 
Result so far: 120123.71762
Deduct 1112 from 1440 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 14:
The number 556 fits into 3280 5 times, leaving a remainder of 500.
Write down 5 as next digit of the result. 
Result so far: 120123.717625
If we subtract 2780 from 3280, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 15:
556 can be fit into 5000 8 times, resulting in a remainder of 552.
Write down 8 as next digit of the result. 
Result so far: 120123.7176258
Subtract 4448 from 5000 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Let's proceed to step 16:
5520 divided by 556 is 9 with a remainder of 516.
Put 9 as the next digit of the answer. 
Result so far: 120123.71762589
If we subtract 5004 from 5520, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

After the division, we end up with 120123.71762589 and a remainder of 5.16e-07.
