14851021 divided by 821 
Let's see how many times 821 fits into 14851021.

Advancing to step 1:
821 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 821

Going ahead to step 2:
821 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 821

Advancing to step 3:
821 can be fit into 148 0 times, resulting in a remainder of 148.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 148 and we're left with 148.
Take the next digit (5) from the dividend and append it to 148, then repeat: 1485 / 821

Let's proceed to step 4:
821 goes into 1485 1 times with a remainder of 664.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 664 after subtracting 821 from 1485.
Grab the next digit (1) from the dividend, add it to 664, then carry on: 6641 / 821

Moving on to step 5:
6641 divided by 821 is 8 with a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 6568 from 6641 and we're left with 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 821

On to step 6:
821 can be fit into 730 0 times, resulting in a remainder of 730.
Put 0 as the next digit of the answer. 
Result so far: 180.0
Subtract 0 from 730 to get 730.
Bring next digit (2) of the dividend behind the 730 and repeat the process: 7302 / 821

Moving on to step 7:
When dividing 7302 by 821, we get 8 with a remainder of 734.
The number 8 becomes the next digit in our result. 
Result so far: 1808.0
Deduct 6568 from 7302 and we're left with 734.
Fetch the next digit (1) from the dividend, attach it to 734 and continue: 7341 / 821

Advancing to step 8:
If we divide 7341 by 821, we get 8 and a remainder of 773.
The number 8 becomes the next digit in our result. 
Result so far: 18088.0
The remainder is 773 after subtracting 6568 from 7341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Advancing to step 9:
The number 821 fits into 7730 9 times, leaving a remainder of 341.
The next digit of our result is 9. 
Result so far: 18088.9
If we take 7389 away from 7730, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 10:
If we divide 3410 by 821, we get 4 and a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 18088.94
If we take 3284 away from 3410, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 11:
When dividing 1260 by 821, we get 1 with a remainder of 439.
Record the quotient 1 as the next digit in the result. 
Result so far: 18088.941
Deduct 821 from 1260 and we're left with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

On to step 12:
If we divide 4390 by 821, we get 5 and a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 18088.9415
Deduct 4105 from 4390 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 13:
821 goes into 2850 3 times with a remainder of 387.
The number 3 becomes the next digit in our result. 
Result so far: 18088.94153
If we subtract 2463 from 2850, we get 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 14:
The number 821 fits into 3870 4 times, leaving a remainder of 586.
Record the quotient 4 as the next digit in the result. 
Result so far: 18088.941534
If we take 3284 away from 3870, we end up with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Advancing to step 15:
821 can be fit into 5860 7 times, resulting in a remainder of 113.
Record the quotient 7 as the next digit in the result. 
Result so far: 18088.9415347
The remainder is 113 after subtracting 5747 from 5860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 16:
821 goes into 1130 1 times with a remainder of 309.
The number 1 becomes the next digit in our result. 
Result so far: 18088.94153471
Deduct 821 from 1130 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

The final result is 18088.94153471 with a remainder of 3.09e-07.
