We're dividing 21956967 by 804 
Let's see how many times 804 fits into 21956967.

Step 1:
The number 804 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
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 / 804

Moving on to step 2:
When dividing 21 by 804, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 804

Moving on to step 3:
804 can be fit into 219 0 times, resulting in a remainder of 219.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 219 to get 219.
Fetch the next digit (5) from the dividend, attach it to 219 and continue: 2195 / 804

On to step 4:
2195 divided by 804 is 2 with a remainder of 587.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1608 from 2195, we get 587.
Grab the next digit (6) from the dividend, add it to 587, then carry on: 5876 / 804

Moving on to step 5:
804 can be fit into 5876 7 times, resulting in a remainder of 248.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 5628 from 5876, we get 248.
Grab the next digit (9) from the dividend, add it to 248, then carry on: 2489 / 804

Moving on to step 6:
804 goes into 2489 3 times with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
Subtracting 2412 from 2489 leaves us with 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 804

On to step 7:
The number 804 fits into 776 0 times, leaving a remainder of 776.
Put 0 as the next digit of the answer. 
Result so far: 2730.0
If we take 0 away from 776, we end up with 776.
Include the next digit (7) from the dividend after 776, then repeat: 7767 / 804

Going ahead to step 8:
The number 804 fits into 7767 9 times, leaving a remainder of 531.
Put 9 as the next digit of the answer. 
Result so far: 27309.0
If we subtract 7236 from 7767, we get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Step 9:
When dividing 5310 by 804, we get 6 with a remainder of 486.
Use 6 as the next digit of our solution. 
Result so far: 27309.6
Subtract 4824 from 5310 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 10:
804 goes into 4860 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 27309.66
The remainder is 36 after subtracting 4824 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 27309.66 with a remainder of 0.036.
