Let's divide 21140729 by 573
We want to figure out the number of times 21140729 can be divided by 573.

Going ahead to step 1:
If we divide 2 by 573, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 573

Moving on to step 2:
When dividing 21 by 573, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 573

Going ahead to step 3:
573 goes into 211 0 times with a remainder of 211.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 211 leaves us with 211.
Take the next digit (4) from the dividend and append it to 211, then repeat: 2114 / 573

Advancing to step 4:
2114 divided by 573 is 3 with a remainder of 395.
The next digit of our result is 3. 
Result so far: 3.0
If we take 1719 away from 2114, we end up with 395.
Bring next digit (0) of the dividend behind the 395 and repeat the process: 3950 / 573

On to step 5:
573 goes into 3950 6 times with a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 3438 from 3950 and we're left with 512.
Grab the next digit (7) from the dividend, add it to 512, then carry on: 5127 / 573

Step 6:
573 can be fit into 5127 8 times, resulting in a remainder of 543.
Record the quotient 8 as the next digit in the result. 
Result so far: 368.0
Subtract 4584 from 5127 to get 543.
Grab the next digit (2) from the dividend, add it to 543, then carry on: 5432 / 573

On to step 7:
If we divide 5432 by 573, we get 9 and a remainder of 275.
Write down 9 as next digit of the result. 
Result so far: 3689.0
If we take 5157 away from 5432, we end up with 275.
Grab the next digit (9) from the dividend, add it to 275, then carry on: 2759 / 573

Advancing to step 8:
2759 divided by 573 is 4 with a remainder of 467.
Put 4 as the next digit of the answer. 
Result so far: 36894.0
Deduct 2292 from 2759 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Moving on to step 9:
If we divide 4670 by 573, we get 8 and a remainder of 86.
The next digit of our result is 8. 
Result so far: 36894.8
Subtract 4584 from 4670 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 10:
If we divide 860 by 573, we get 1 and a remainder of 287.
Write down 1 as next digit of the result. 
Result so far: 36894.81
Deduct 573 from 860 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 11:
If we divide 2870 by 573, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 36894.815
Subtract 2865 from 2870 to 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.

Let's proceed to step 12:
When dividing 50 by 573, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 36894.815
If we subtract 0 from 50, 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 13:
573 goes into 500 0 times with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 36894.815
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 outcome is 36894.815, with a leftover of 0.0005.
