Let's divide 21616074 by 815
Let's see how many times 815 fits into 21616074.

Going ahead to step 1:
If we divide 2 by 815, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 815

Moving on to step 2:
815 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 815

On to step 3:
If we divide 216 by 815, we get 0 and a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Fetch the next digit (1) from the dividend, attach it to 216 and continue: 2161 / 815

On to step 4:
2161 divided by 815 is 2 with a remainder of 531.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1630 away from 2161, we end up with 531.
Take the next digit (6) from the dividend and append it to 531, then repeat: 5316 / 815

On to step 5:
5316 divided by 815 is 6 with a remainder of 426.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 4890 from 5316 to get 426.
Append the next digit (0) from the dividend to 426 and continue with: 4260 / 815

Step 6:
4260 divided by 815 is 5 with a remainder of 185.
The next digit of our result is 5. 
Result so far: 265.0
Deduct 4075 from 4260 and we're left with 185.
Fetch the next digit (7) from the dividend, attach it to 185 and continue: 1857 / 815

On to step 7:
If we divide 1857 by 815, we get 2 and a remainder of 227.
The number 2 becomes the next digit in our result. 
Result so far: 2652.0
Deduct 1630 from 1857 and we're left with 227.
Bring next digit (4) of the dividend behind the 227 and repeat the process: 2274 / 815

Let's proceed to step 8:
When dividing 2274 by 815, we get 2 with a remainder of 644.
Record the quotient 2 as the next digit in the result. 
Result so far: 26522.0
Deduct 1630 from 2274 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Moving on to step 9:
If we divide 6440 by 815, we get 7 and a remainder of 735.
Record the quotient 7 as the next digit in the result. 
Result so far: 26522.7
If we subtract 5705 from 6440, we get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Moving on to step 10:
When dividing 7350 by 815, we get 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 26522.79
Subtracting 7335 from 7350 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
If we divide 150 by 815, we get 0 and a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 26522.79
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 12:
1500 divided by 815 is 1 with a remainder of 685.
The next digit of our result is 1. 
Result so far: 26522.7901
If we take 815 away from 1500, we end up with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 13:
The number 815 fits into 6850 8 times, leaving a remainder of 330.
The number 8 becomes the next digit in our result. 
Result so far: 26522.79018
If we take 6520 away from 6850, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 14:
When dividing 3300 by 815, we get 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 26522.790184
Deduct 3260 from 3300 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
When dividing 400 by 815, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 26522.790184
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 16:
The number 815 fits into 4000 4 times, leaving a remainder of 740.
Put 4 as the next digit of the answer. 
Result so far: 26522.79018404
Subtracting 3260 from 4000 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

The quotient of the division is 26522.79018404, and the remainder is 7.4e-07.
