15621279 ÷ 827 
Let's see how many times 827 fits into 15621279.

On to step 1:
827 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 827

Advancing to step 2:
15 divided by 827 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 827

Advancing to step 3:
827 can be fit into 156 0 times, resulting in a remainder of 156.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 156, we end up with 156.
Grab the next digit (2) from the dividend, add it to 156, then carry on: 1562 / 827

Advancing to step 4:
827 goes into 1562 1 times with a remainder of 735.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 827 from 1562 leaves us with 735.
Take the next digit (1) from the dividend and append it to 735, then repeat: 7351 / 827

On to step 5:
If we divide 7351 by 827, we get 8 and a remainder of 735.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 6616 from 7351 and we're left with 735.
Append the next digit (2) from the dividend to 735 and continue with: 7352 / 827

Advancing to step 6:
827 can be fit into 7352 8 times, resulting in a remainder of 736.
Put 8 as the next digit of the answer. 
Result so far: 188.0
If we take 6616 away from 7352, we end up with 736.
Take the next digit (7) from the dividend and append it to 736, then repeat: 7367 / 827

On to step 7:
If we divide 7367 by 827, we get 8 and a remainder of 751.
Put 8 as the next digit of the answer. 
Result so far: 1888.0
The remainder is 751 after subtracting 6616 from 7367.
Append the next digit (9) from the dividend to 751 and continue with: 7519 / 827

Step 8:
7519 divided by 827 is 9 with a remainder of 76.
The next digit of our result is 9. 
Result so far: 18889.0
If we subtract 7443 from 7519, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
When dividing 760 by 827, we get 0 with a remainder of 760.
Record the quotient 0 as the next digit in the result. 
Result so far: 18889.0
The remainder is 760 after subtracting 0 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 10:
The number 827 fits into 7600 9 times, leaving a remainder of 157.
Write down 9 as next digit of the result. 
Result so far: 18889.09
Subtract 7443 from 7600 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 11:
1570 divided by 827 is 1 with a remainder of 743.
Use 1 as the next digit of our solution. 
Result so far: 18889.091
If we take 827 away from 1570, we end up with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Moving on to step 12:
The number 827 fits into 7430 8 times, leaving a remainder of 814.
Write down 8 as next digit of the result. 
Result so far: 18889.0918
If we subtract 6616 from 7430, we get 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Let's proceed to step 13:
8140 divided by 827 is 9 with a remainder of 697.
The number 9 becomes the next digit in our result. 
Result so far: 18889.09189
Subtracting 7443 from 8140 leaves us with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Moving on to step 14:
827 can be fit into 6970 8 times, resulting in a remainder of 354.
The next digit of our result is 8. 
Result so far: 18889.091898
If we take 6616 away from 6970, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 15:
The number 827 fits into 3540 4 times, leaving a remainder of 232.
The number 4 becomes the next digit in our result. 
Result so far: 18889.0918984
The remainder is 232 after subtracting 3308 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 16:
If we divide 2320 by 827, we get 2 and a remainder of 666.
The number 2 becomes the next digit in our result. 
Result so far: 18889.09189842
Deduct 1654 from 2320 and we're left with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

The final outcome is 18889.09189842, with a leftover of 6.66e-07.
