Let's divide 15815786 by 555
We want to divide 15815786 by 555.

Moving on to step 1:
555 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 555

On to step 2:
555 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 555

Going ahead to step 3:
The number 555 fits into 158 0 times, leaving a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 158 leaves us with 158.
Include the next digit (1) from the dividend after 158, then repeat: 1581 / 555

Going ahead to step 4:
555 can be fit into 1581 2 times, resulting in a remainder of 471.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1110 away from 1581, we end up with 471.
Append the next digit (5) from the dividend to 471 and continue with: 4715 / 555

Going ahead to step 5:
If we divide 4715 by 555, we get 8 and a remainder of 275.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 4440 away from 4715, we end up with 275.
Grab the next digit (7) from the dividend, add it to 275, then carry on: 2757 / 555

Let's proceed to step 6:
555 goes into 2757 4 times with a remainder of 537.
Use 4 as the next digit of our solution. 
Result so far: 284.0
The remainder is 537 after subtracting 2220 from 2757.
Include the next digit (8) from the dividend after 537, then repeat: 5378 / 555

Let's proceed to step 7:
If we divide 5378 by 555, we get 9 and a remainder of 383.
Record the quotient 9 as the next digit in the result. 
Result so far: 2849.0
Deduct 4995 from 5378 and we're left with 383.
Grab the next digit (6) from the dividend, add it to 383, then carry on: 3836 / 555

Advancing to step 8:
The number 555 fits into 3836 6 times, leaving a remainder of 506.
Write down 6 as next digit of the result. 
Result so far: 28496.0
The remainder is 506 after subtracting 3330 from 3836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 9:
555 goes into 5060 9 times with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 28496.9
Subtracting 4995 from 5060 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
650 divided by 555 is 1 with a remainder of 95.
Write down 1 as next digit of the result. 
Result so far: 28496.91
The remainder is 95 after subtracting 555 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 11:
The number 555 fits into 950 1 times, leaving a remainder of 395.
Put 1 as the next digit of the answer. 
Result so far: 28496.911
If we take 555 away from 950, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

The final outcome is 28496.911, with a leftover of 0.0395.
