We're dividing 21120209 by 192 
We're looking to find how many times 192 goes into 21120209.

On to step 1:
When dividing 2 by 192, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 192

Moving on to step 2:
192 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 192

Going ahead to step 3:
The number 192 fits into 211 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 192 from 211 and we're left with 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 192

Advancing to step 4:
The number 192 fits into 192 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 0 after subtracting 192 from 192.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 192

Let's proceed to step 5:
The number 192 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 192

Going ahead to step 6:
When dividing 2 by 192, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 1100.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 192

On to step 7:
192 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 11000.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 192

On to step 8:
When dividing 209 by 192, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 110001.0
The remainder is 17 after subtracting 192 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
192 can be fit into 170 0 times, resulting in a remainder of 170.
The next digit of our result is 0. 
Result so far: 110001.0
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 10:
If we divide 1700 by 192, we get 8 and a remainder of 164.
The number 8 becomes the next digit in our result. 
Result so far: 110001.08
Subtract 1536 from 1700 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 11:
192 can be fit into 1640 8 times, resulting in a remainder of 104.
Write down 8 as next digit of the result. 
Result so far: 110001.088
If we subtract 1536 from 1640, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 110001.088, and the remainder is 0.0104.
