Let's divide 19927872 by 921
Let's see how many times 921 fits into 19927872.

Step 1:
921 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 921

Let's proceed to step 2:
921 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 921

Let's proceed to step 3:
199 divided by 921 is 0 with a remainder of 199.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 199 after subtracting 0 from 199.
Include the next digit (2) from the dividend after 199, then repeat: 1992 / 921

Going ahead to step 4:
The number 921 fits into 1992 2 times, leaving a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1842 from 1992 and we're left with 150.
Bring next digit (7) of the dividend behind the 150 and repeat the process: 1507 / 921

Let's proceed to step 5:
921 can be fit into 1507 1 times, resulting in a remainder of 586.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 586 after subtracting 921 from 1507.
Append the next digit (8) from the dividend to 586 and continue with: 5868 / 921

On to step 6:
If we divide 5868 by 921, we get 6 and a remainder of 342.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
If we subtract 5526 from 5868, we get 342.
Fetch the next digit (7) from the dividend, attach it to 342 and continue: 3427 / 921

Advancing to step 7:
921 goes into 3427 3 times with a remainder of 664.
Use 3 as the next digit of our solution. 
Result so far: 2163.0
Subtracting 2763 from 3427 leaves us with 664.
Include the next digit (2) from the dividend after 664, then repeat: 6642 / 921

Let's proceed to step 8:
If we divide 6642 by 921, we get 7 and a remainder of 195.
Record the quotient 7 as the next digit in the result. 
Result so far: 21637.0
If we take 6447 away from 6642, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 9:
If we divide 1950 by 921, we get 2 and a remainder of 108.
Write down 2 as next digit of the result. 
Result so far: 21637.2
Subtract 1842 from 1950 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 10:
The number 921 fits into 1080 1 times, leaving a remainder of 159.
Use 1 as the next digit of our solution. 
Result so far: 21637.21
If we take 921 away from 1080, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 11:
921 can be fit into 1590 1 times, resulting in a remainder of 669.
Put 1 as the next digit of the answer. 
Result so far: 21637.211
Subtract 921 from 1590 to get 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

The final result is 21637.211 with a remainder of 0.0669.
