27316843 divided by 21 
We're looking to find how many times 21 goes into 27316843.

On to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 21

Advancing to step 2:
The number 21 fits into 27 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 21 from 27, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 21

Going ahead to step 3:
63 divided by 21 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 63 from 63, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 21

On to step 4:
When dividing 1 by 21, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 130.0
If we take 0 away from 1, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 21

On to step 5:
The number 21 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 1300.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 21

Moving on to step 6:
When dividing 168 by 21, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 13008.0
Deduct 168 from 168 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 21

Advancing to step 7:
21 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 130080.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 21

Going ahead to step 8:
If we divide 43 by 21, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 1300802.0
Subtracting 42 from 43 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 21, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1300802.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
When dividing 100 by 21, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1300802.04
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
If we divide 160 by 21, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 1300802.047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
21 goes into 130 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 1300802.0476
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
40 divided by 21 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1300802.04761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 1300802.047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 15:
21 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 1300802.047619
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 16:
If we divide 100 by 21, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1300802.04761904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 1300802.04761904 with a balance of 1.6e-08.
