21480191 ÷ 192 
We want to divide 21480191 by 192.

On to step 1:
If we divide 2 by 192, 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.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 192

Going ahead to step 2:
192 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 192

Moving on to step 3:
192 can be fit into 214 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 192 away from 214, we end up with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 192

Going ahead to step 4:
If we divide 228 by 192, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 192 from 228, we get 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 192

Let's proceed to step 5:
192 goes into 360 1 times with a remainder of 168.
Use 1 as the next digit of our solution. 
Result so far: 111.0
If we subtract 192 from 360, we get 168.
Grab the next digit (1) from the dividend, add it to 168, then carry on: 1681 / 192

On to step 6:
1681 divided by 192 is 8 with a remainder of 145.
Put 8 as the next digit of the answer. 
Result so far: 1118.0
The remainder is 145 after subtracting 1536 from 1681.
Bring next digit (9) of the dividend behind the 145 and repeat the process: 1459 / 192

Going ahead to step 7:
The number 192 fits into 1459 7 times, leaving a remainder of 115.
Record the quotient 7 as the next digit in the result. 
Result so far: 11187.0
Deduct 1344 from 1459 and we're left with 115.
Grab the next digit (1) from the dividend, add it to 115, then carry on: 1151 / 192

Let's proceed to step 8:
The number 192 fits into 1151 5 times, leaving a remainder of 191.
Use 5 as the next digit of our solution. 
Result so far: 111875.0
If we subtract 960 from 1151, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 9:
1910 divided by 192 is 9 with a remainder of 182.
Write down 9 as next digit of the result. 
Result so far: 111875.9
If we take 1728 away from 1910, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 10:
192 can be fit into 1820 9 times, resulting in a remainder of 92.
The number 9 becomes the next digit in our result. 
Result so far: 111875.99
If we subtract 1728 from 1820, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

After the division, we end up with 111875.99 and a remainder of 0.092.
