We're dividing 41521881 by 821 
We want to figure out the number of times 41521881 can be divided by 821.

Step 1:
When dividing 4 by 821, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 821

On to step 2:
The number 821 fits into 41 0 times, leaving a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Take the next digit (5) from the dividend and append it to 41, then repeat: 415 / 821

Going ahead to step 3:
When dividing 415 by 821, we get 0 with a remainder of 415.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 415 after subtracting 0 from 415.
Append the next digit (2) from the dividend to 415 and continue with: 4152 / 821

On to step 4:
821 goes into 4152 5 times with a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 4105 from 4152, we get 47.
Fetch the next digit (1) from the dividend, attach it to 47 and continue: 471 / 821

On to step 5:
821 goes into 471 0 times with a remainder of 471.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtracting 0 from 471 leaves us with 471.
Include the next digit (8) from the dividend after 471, then repeat: 4718 / 821

Step 6:
821 can be fit into 4718 5 times, resulting in a remainder of 613.
Record the quotient 5 as the next digit in the result. 
Result so far: 505.0
Deduct 4105 from 4718 and we're left with 613.
Grab the next digit (8) from the dividend, add it to 613, then carry on: 6138 / 821

On to step 7:
821 goes into 6138 7 times with a remainder of 391.
The next digit of our result is 7. 
Result so far: 5057.0
Subtract 5747 from 6138 to get 391.
Append the next digit (1) from the dividend to 391 and continue with: 3911 / 821

Advancing to step 8:
821 can be fit into 3911 4 times, resulting in a remainder of 627.
Put 4 as the next digit of the answer. 
Result so far: 50574.0
Deduct 3284 from 3911 and we're left with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Going ahead to step 9:
821 can be fit into 6270 7 times, resulting in a remainder of 523.
The number 7 becomes the next digit in our result. 
Result so far: 50574.7
The remainder is 523 after subtracting 5747 from 6270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Step 10:
821 goes into 5230 6 times with a remainder of 304.
The number 6 becomes the next digit in our result. 
Result so far: 50574.76
Subtracting 4926 from 5230 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 11:
If we divide 3040 by 821, we get 3 and a remainder of 577.
Put 3 as the next digit of the answer. 
Result so far: 50574.763
If we subtract 2463 from 3040, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Let's proceed to step 12:
5770 divided by 821 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 50574.7637
If we take 5747 away from 5770, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
If we divide 230 by 821, we get 0 and a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 50574.7637
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 14:
821 can be fit into 2300 2 times, resulting in a remainder of 658.
Record the quotient 2 as the next digit in the result. 
Result so far: 50574.763702
The remainder is 658 after subtracting 1642 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Going ahead to step 15:
If we divide 6580 by 821, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 50574.7637028
Subtracting 6568 from 6580 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 16:
The number 821 fits into 120 0 times, leaving a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 50574.7637028
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 50574.7637028 with a remainder of 1.2e-07.
