Let's divide 21043127 by 571
We're looking to find how many times 571 goes into 21043127.

Moving on to step 1:
If we divide 2 by 571, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 571

Step 2:
571 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 571

Moving on to step 3:
210 divided by 571 is 0 with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 210 after subtracting 0 from 210.
Bring next digit (4) of the dividend behind the 210 and repeat the process: 2104 / 571

Let's proceed to step 4:
If we divide 2104 by 571, we get 3 and a remainder of 391.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1713 away from 2104, we end up with 391.
Include the next digit (3) from the dividend after 391, then repeat: 3913 / 571

Advancing to step 5:
571 goes into 3913 6 times with a remainder of 487.
Write down 6 as next digit of the result. 
Result so far: 36.0
The remainder is 487 after subtracting 3426 from 3913.
Take the next digit (1) from the dividend and append it to 487, then repeat: 4871 / 571

Advancing to step 6:
4871 divided by 571 is 8 with a remainder of 303.
The next digit of our result is 8. 
Result so far: 368.0
The remainder is 303 after subtracting 4568 from 4871.
Grab the next digit (2) from the dividend, add it to 303, then carry on: 3032 / 571

Moving on to step 7:
571 goes into 3032 5 times with a remainder of 177.
The number 5 becomes the next digit in our result. 
Result so far: 3685.0
Subtracting 2855 from 3032 leaves us with 177.
Include the next digit (7) from the dividend after 177, then repeat: 1777 / 571

Going ahead to step 8:
571 can be fit into 1777 3 times, resulting in a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 36853.0
Deduct 1713 from 1777 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
The number 571 fits into 640 1 times, leaving a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 36853.1
Subtract 571 from 640 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 10:
If we divide 690 by 571, we get 1 and a remainder of 119.
The number 1 becomes the next digit in our result. 
Result so far: 36853.11
If we subtract 571 from 690, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

The final outcome is 36853.11, with a leftover of 0.119.
