Let's divide 21916278 by 873
Let's see how many times 873 fits into 21916278.

Advancing to step 1:
2 divided by 873 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 873

On to step 2:
The number 873 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 873

On to step 3:
219 divided by 873 is 0 with a remainder of 219.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 219, we end up with 219.
Bring next digit (1) of the dividend behind the 219 and repeat the process: 2191 / 873

Let's proceed to step 4:
873 goes into 2191 2 times with a remainder of 445.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1746 from 2191 and we're left with 445.
Bring next digit (6) of the dividend behind the 445 and repeat the process: 4456 / 873

On to step 5:
873 goes into 4456 5 times with a remainder of 91.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 91 after subtracting 4365 from 4456.
Grab the next digit (2) from the dividend, add it to 91, then carry on: 912 / 873

On to step 6:
912 divided by 873 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 251.0
Subtracting 873 from 912 leaves us with 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 873

Let's proceed to step 7:
873 goes into 397 0 times with a remainder of 397.
The number 0 becomes the next digit in our result. 
Result so far: 2510.0
If we subtract 0 from 397, we get 397.
Bring next digit (8) of the dividend behind the 397 and repeat the process: 3978 / 873

Moving on to step 8:
873 can be fit into 3978 4 times, resulting in a remainder of 486.
Use 4 as the next digit of our solution. 
Result so far: 25104.0
Subtracting 3492 from 3978 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Going ahead to step 9:
The number 873 fits into 4860 5 times, leaving a remainder of 495.
Put 5 as the next digit of the answer. 
Result so far: 25104.5
If we subtract 4365 from 4860, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Moving on to step 10:
873 goes into 4950 5 times with a remainder of 585.
The number 5 becomes the next digit in our result. 
Result so far: 25104.55
Deduct 4365 from 4950 and we're left with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

The final result is 25104.55 with a remainder of 0.585.
