We look at the division of 21641181 by 572 
We want to figure out the number of times 21641181 can be divided by 572.

Moving on to step 1:
572 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 572

Moving on to step 2:
The number 572 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 572

Moving on to step 3:
216 divided by 572 is 0 with a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Append the next digit (4) from the dividend to 216 and continue with: 2164 / 572

Step 4:
If we divide 2164 by 572, we get 3 and a remainder of 448.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1716 away from 2164, we end up with 448.
Fetch the next digit (1) from the dividend, attach it to 448 and continue: 4481 / 572

Step 5:
572 can be fit into 4481 7 times, resulting in a remainder of 477.
Write down 7 as next digit of the result. 
Result so far: 37.0
Deduct 4004 from 4481 and we're left with 477.
Bring next digit (1) of the dividend behind the 477 and repeat the process: 4771 / 572

Step 6:
572 goes into 4771 8 times with a remainder of 195.
Record the quotient 8 as the next digit in the result. 
Result so far: 378.0
If we take 4576 away from 4771, we end up with 195.
Include the next digit (8) from the dividend after 195, then repeat: 1958 / 572

On to step 7:
572 goes into 1958 3 times with a remainder of 242.
Put 3 as the next digit of the answer. 
Result so far: 3783.0
Deduct 1716 from 1958 and we're left with 242.
Bring next digit (1) of the dividend behind the 242 and repeat the process: 2421 / 572

Moving on to step 8:
If we divide 2421 by 572, we get 4 and a remainder of 133.
Put 4 as the next digit of the answer. 
Result so far: 37834.0
The remainder is 133 after subtracting 2288 from 2421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 9:
If we divide 1330 by 572, we get 2 and a remainder of 186.
The next digit of our result is 2. 
Result so far: 37834.2
If we subtract 1144 from 1330, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 10:
The number 572 fits into 1860 3 times, leaving a remainder of 144.
The next digit of our result is 3. 
Result so far: 37834.23
Subtracting 1716 from 1860 leaves us 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.

Going ahead to step 11:
If we divide 1440 by 572, we get 2 and a remainder of 296.
Use 2 as the next digit of our solution. 
Result so far: 37834.232
The remainder is 296 after subtracting 1144 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 12:
If we divide 2960 by 572, we get 5 and a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 37834.2325
Deduct 2860 from 2960 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
1000 divided by 572 is 1 with a remainder of 428.
Write down 1 as next digit of the result. 
Result so far: 37834.23251
Subtract 572 from 1000 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 14:
572 goes into 4280 7 times with a remainder of 276.
Use 7 as the next digit of our solution. 
Result so far: 37834.232517
Subtract 4004 from 4280 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 15:
If we divide 2760 by 572, we get 4 and a remainder of 472.
Record the quotient 4 as the next digit in the result. 
Result so far: 37834.2325174
The remainder is 472 after subtracting 2288 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 16:
572 can be fit into 4720 8 times, resulting in a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 37834.23251748
If we take 4576 away from 4720, 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.

The final result is 37834.23251748 with a remainder of 1.44e-07.
