We look at the division of 21908716 by 281 
We're looking to find how many times 281 goes into 21908716.

Going ahead to step 1:
The number 281 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 281

Moving on to step 2:
When dividing 21 by 281, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
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 / 281

Step 3:
219 divided by 281 is 0 with a remainder of 219.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 219 after subtracting 0 from 219.
Grab the next digit (0) from the dividend, add it to 219, then carry on: 2190 / 281

Step 4:
If we divide 2190 by 281, we get 7 and a remainder of 223.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 223 after subtracting 1967 from 2190.
Grab the next digit (8) from the dividend, add it to 223, then carry on: 2238 / 281

On to step 5:
If we divide 2238 by 281, we get 7 and a remainder of 271.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 1967 from 2238 leaves us with 271.
Take the next digit (7) from the dividend and append it to 271, then repeat: 2717 / 281

Let's proceed to step 6:
If we divide 2717 by 281, we get 9 and a remainder of 188.
Use 9 as the next digit of our solution. 
Result so far: 779.0
If we subtract 2529 from 2717, we get 188.
Grab the next digit (1) from the dividend, add it to 188, then carry on: 1881 / 281

On to step 7:
281 goes into 1881 6 times with a remainder of 195.
The next digit of our result is 6. 
Result so far: 7796.0
Subtract 1686 from 1881 to get 195.
Append the next digit (6) from the dividend to 195 and continue with: 1956 / 281

Moving on to step 8:
281 goes into 1956 6 times with a remainder of 270.
Use 6 as the next digit of our solution. 
Result so far: 77966.0
Subtract 1686 from 1956 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 9:
If we divide 2700 by 281, we get 9 and a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 77966.9
Deduct 2529 from 2700 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 10:
The number 281 fits into 1710 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 77966.96
The remainder is 24 after subtracting 1686 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
281 goes into 240 0 times with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 77966.96
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
281 goes into 2400 8 times with a remainder of 152.
Put 8 as the next digit of the answer. 
Result so far: 77966.9608
If we subtract 2248 from 2400, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 13:
281 can be fit into 1520 5 times, resulting in a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 77966.96085
Deduct 1405 from 1520 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 14:
When dividing 1150 by 281, we get 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 77966.960854
If we take 1124 away from 1150, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 15:
281 can be fit into 260 0 times, resulting in a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 77966.960854
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 16:
When dividing 2600 by 281, we get 9 with a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 77966.96085409
The remainder is 71 after subtracting 2529 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final outcome is 77966.96085409, with a leftover of 7.1e-08.
