The number 571 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 571

Advancing to step 2:
The number 571 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 571

Let's proceed to step 3:
571 goes into 135 0 times with a remainder of 135.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 135 to get 135.
Fetch the next digit (5) from the dividend, attach it to 135 and continue: 1355 / 571

On to step 4:
If we divide 1355 by 571, we get 2 and a remainder of 213.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1142 from 1355 leaves us with 213.
Fetch the next digit (6) from the dividend, attach it to 213 and continue: 2136 / 571

Let's proceed to step 5:
The number 571 fits into 2136 3 times, leaving a remainder of 423.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 1713 from 2136 to get 423.
Grab the next digit (7) from the dividend, add it to 423, then carry on: 4237 / 571

Going ahead to step 6:
The number 571 fits into 4237 7 times, leaving a remainder of 240.
Record the quotient 7 as the next digit in the result. 
Result so far: 237.0
If we subtract 3997 from 4237, we get 240.
Bring next digit (6) of the dividend behind the 240 and repeat the process: 2406 / 571

Let's proceed to step 7:
571 can be fit into 2406 4 times, resulting in a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 2374.0
If we take 2284 away from 2406, we end up with 122.
Include the next digit (1) from the dividend after 122, then repeat: 1221 / 571

Going ahead to step 8:
571 goes into 1221 2 times with a remainder of 79.
Record the quotient 2 as the next digit in the result. 
Result so far: 23742.0
Deduct 1142 from 1221 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
571 goes into 790 1 times with a remainder of 219.
Put 1 as the next digit of the answer. 
Result so far: 23742.1
Subtract 571 from 790 to get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 10:
571 can be fit into 2190 3 times, resulting in a remainder of 477.
Use 3 as the next digit of our solution. 
Result so far: 23742.13
The remainder is 477 after subtracting 1713 from 2190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Going ahead to step 11:
The number 571 fits into 4770 8 times, leaving a remainder of 202.
Record the quotient 8 as the next digit in the result. 
Result so far: 23742.138
Deduct 4568 from 4770 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 12:
When dividing 2020 by 571, we get 3 with a remainder of 307.
Put 3 as the next digit of the answer. 
Result so far: 23742.1383
If we take 1713 away from 2020, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 13:
If we divide 3070 by 571, we get 5 and a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 23742.13835
The remainder is 215 after subtracting 2855 from 3070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 14:
If we divide 2150 by 571, we get 3 and a remainder of 437.
The number 3 becomes the next digit in our result. 
Result so far: 23742.138353
The remainder is 437 after subtracting 1713 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 15:
When dividing 4370 by 571, we get 7 with a remainder of 373.
Put 7 as the next digit of the answer. 
Result so far: 23742.1383537
Subtract 3997 from 4370 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 16:
571 can be fit into 3730 6 times, resulting in a remainder of 304.
Write down 6 as next digit of the result. 
Result so far: 23742.13835376
Subtracting 3426 from 3730 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Our division results in 23742.13835376 with a remaining 3.04e-07.
