The number 821 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 821

Going ahead to step 3:
When dividing 409 by 821, we get 0 with a remainder of 409.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 409 to get 409.
Grab the next digit (1) from the dividend, add it to 409, then carry on: 4091 / 821

Step 4:
821 can be fit into 4091 4 times, resulting in a remainder of 807.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3284 from 4091 leaves us with 807.
Include the next digit (7) from the dividend after 807, then repeat: 8077 / 821

Going ahead to step 5:
When dividing 8077 by 821, we get 9 with a remainder of 688.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Subtracting 7389 from 8077 leaves us with 688.
Append the next digit (4) from the dividend to 688 and continue with: 6884 / 821

Advancing to step 6:
821 goes into 6884 8 times with a remainder of 316.
The number 8 becomes the next digit in our result. 
Result so far: 498.0
If we take 6568 away from 6884, we end up with 316.
Append the next digit (4) from the dividend to 316 and continue with: 3164 / 821

Going ahead to step 7:
If we divide 3164 by 821, we get 3 and a remainder of 701.
Put 3 as the next digit of the answer. 
Result so far: 4983.0
Deduct 2463 from 3164 and we're left with 701.
Include the next digit (3) from the dividend after 701, then repeat: 7013 / 821

Step 8:
821 goes into 7013 8 times with a remainder of 445.
Use 8 as the next digit of our solution. 
Result so far: 49838.0
If we subtract 6568 from 7013, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 9:
821 goes into 4450 5 times with a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 49838.5
The remainder is 345 after subtracting 4105 from 4450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 10:
The number 821 fits into 3450 4 times, leaving a remainder of 166.
Write down 4 as next digit of the result. 
Result so far: 49838.54
The remainder is 166 after subtracting 3284 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 11:
The number 821 fits into 1660 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 49838.542
Deduct 1642 from 1660 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
If we divide 180 by 821, we get 0 and a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 49838.542
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 13:
821 goes into 1800 2 times with a remainder of 158.
The next digit of our result is 2. 
Result so far: 49838.54202
If we subtract 1642 from 1800, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 14:
When dividing 1580 by 821, we get 1 with a remainder of 759.
Record the quotient 1 as the next digit in the result. 
Result so far: 49838.542021
Subtracting 821 from 1580 leaves us with 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Step 15:
If we divide 7590 by 821, we get 9 and a remainder of 201.
Record the quotient 9 as the next digit in the result. 
Result so far: 49838.5420219
Subtract 7389 from 7590 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 16:
2010 divided by 821 is 2 with a remainder of 368.
Write down 2 as next digit of the result. 
Result so far: 49838.54202192
If we subtract 1642 from 2010, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Our division results in 49838.54202192 with a remaining 3.68e-07.
