8724085 divided by 821 
Our goal is to divide 8724085 by 821.

On to step 1:
If we divide 8 by 821, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 821

Going ahead to step 2:
The number 821 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Bring next digit (2) of the dividend behind the 87 and repeat the process: 872 / 821

Step 3:
The number 821 fits into 872 1 times, leaving a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 821 from 872 to get 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 821

Advancing to step 4:
The number 821 fits into 514 0 times, leaving a remainder of 514.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 514 after subtracting 0 from 514.
Fetch the next digit (0) from the dividend, attach it to 514 and continue: 5140 / 821

Let's proceed to step 5:
821 can be fit into 5140 6 times, resulting in a remainder of 214.
Write down 6 as next digit of the result. 
Result so far: 106.0
The remainder is 214 after subtracting 4926 from 5140.
Grab the next digit (8) from the dividend, add it to 214, then carry on: 2148 / 821

Moving on to step 6:
If we divide 2148 by 821, we get 2 and a remainder of 506.
The number 2 becomes the next digit in our result. 
Result so far: 1062.0
The remainder is 506 after subtracting 1642 from 2148.
Append the next digit (5) from the dividend to 506 and continue with: 5065 / 821

Advancing to step 7:
821 goes into 5065 6 times with a remainder of 139.
Put 6 as the next digit of the answer. 
Result so far: 10626.0
Subtracting 4926 from 5065 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Moving on to step 8:
If we divide 1390 by 821, we get 1 and a remainder of 569.
Use 1 as the next digit of our solution. 
Result so far: 10626.1
Subtract 821 from 1390 to get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Going ahead to step 9:
If we divide 5690 by 821, we get 6 and a remainder of 764.
Write down 6 as next digit of the result. 
Result so far: 10626.16
The remainder is 764 after subtracting 4926 from 5690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Let's proceed to step 10:
If we divide 7640 by 821, we get 9 and a remainder of 251.
The next digit of our result is 9. 
Result so far: 10626.169
If we take 7389 away from 7640, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 11:
821 goes into 2510 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 10626.1693
Deduct 2463 from 2510 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 12:
821 can be fit into 470 0 times, resulting in a remainder of 470.
Put 0 as the next digit of the answer. 
Result so far: 10626.1693
The remainder is 470 after subtracting 0 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 13:
4700 divided by 821 is 5 with a remainder of 595.
Put 5 as the next digit of the answer. 
Result so far: 10626.169305
Subtract 4105 from 4700 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 14:
821 can be fit into 5950 7 times, resulting in a remainder of 203.
The next digit of our result is 7. 
Result so far: 10626.1693057
If we take 5747 away from 5950, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 15:
821 goes into 2030 2 times with a remainder of 388.
Use 2 as the next digit of our solution. 
Result so far: 10626.16930572
Subtracting 1642 from 2030 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The quotient of the division is 10626.16930572, and the remainder is 3.88e-07.
