53985299 ÷ 555 
We want to divide 53985299 by 555.

On to step 1:
555 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 555

On to step 2:
If we divide 53 by 555, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 555

Moving on to step 3:
539 divided by 555 is 0 with a remainder of 539.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 539 to get 539.
Grab the next digit (8) from the dividend, add it to 539, then carry on: 5398 / 555

Step 4:
555 goes into 5398 9 times with a remainder of 403.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 4995 from 5398, we get 403.
Bring next digit (5) of the dividend behind the 403 and repeat the process: 4035 / 555

On to step 5:
When dividing 4035 by 555, we get 7 with a remainder of 150.
Write down 7 as next digit of the result. 
Result so far: 97.0
If we take 3885 away from 4035, we end up with 150.
Grab the next digit (2) from the dividend, add it to 150, then carry on: 1502 / 555

Moving on to step 6:
When dividing 1502 by 555, we get 2 with a remainder of 392.
Record the quotient 2 as the next digit in the result. 
Result so far: 972.0
If we subtract 1110 from 1502, we get 392.
Fetch the next digit (9) from the dividend, attach it to 392 and continue: 3929 / 555

On to step 7:
When dividing 3929 by 555, we get 7 with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 9727.0
If we take 3885 away from 3929, we end up with 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 555

Moving on to step 8:
555 can be fit into 449 0 times, resulting in a remainder of 449.
The next digit of our result is 0. 
Result so far: 97270.0
If we subtract 0 from 449, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 9:
555 goes into 4490 8 times with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 97270.8
If we subtract 4440 from 4490, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
When dividing 500 by 555, we get 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 97270.8
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 11:
If we divide 5000 by 555, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 97270.809
If we subtract 4995 from 5000, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
50 divided by 555 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 97270.809
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
555 goes into 500 0 times with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 97270.809
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 97270.809 with a remainder of 0.0005.
