41986424 divided by 821 
We want to figure out the number of times 41986424 can be divided by 821.

On to step 1:
When dividing 4 by 821, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 821

Step 2:
When dividing 41 by 821, we get 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Append the next digit (9) from the dividend to 41 and continue with: 419 / 821

Step 3:
419 divided by 821 is 0 with a remainder of 419.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 419 and we're left with 419.
Bring next digit (8) of the dividend behind the 419 and repeat the process: 4198 / 821

Let's proceed to step 4:
821 goes into 4198 5 times with a remainder of 93.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 93 after subtracting 4105 from 4198.
Append the next digit (6) from the dividend to 93 and continue with: 936 / 821

Advancing to step 5:
936 divided by 821 is 1 with a remainder of 115.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtracting 821 from 936 leaves us with 115.
Grab the next digit (4) from the dividend, add it to 115, then carry on: 1154 / 821

Step 6:
If we divide 1154 by 821, we get 1 and a remainder of 333.
Use 1 as the next digit of our solution. 
Result so far: 511.0
Subtract 821 from 1154 to get 333.
Bring next digit (2) of the dividend behind the 333 and repeat the process: 3332 / 821

Advancing to step 7:
If we divide 3332 by 821, we get 4 and a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 5114.0
If we subtract 3284 from 3332, we get 48.
Take the next digit (4) from the dividend and append it to 48, then repeat: 484 / 821

On to step 8:
When dividing 484 by 821, we get 0 with a remainder of 484.
Write down 0 as next digit of the result. 
Result so far: 51140.0
Subtract 0 from 484 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 9:
When dividing 4840 by 821, we get 5 with a remainder of 735.
Put 5 as the next digit of the answer. 
Result so far: 51140.5
Deduct 4105 from 4840 and we're left with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Advancing to step 10:
If we divide 7350 by 821, we get 8 and a remainder of 782.
Put 8 as the next digit of the answer. 
Result so far: 51140.58
If we subtract 6568 from 7350, we get 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Step 11:
821 can be fit into 7820 9 times, resulting in a remainder of 431.
Record the quotient 9 as the next digit in the result. 
Result so far: 51140.589
The remainder is 431 after subtracting 7389 from 7820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Advancing to step 12:
821 can be fit into 4310 5 times, resulting in a remainder of 205.
Write down 5 as next digit of the result. 
Result so far: 51140.5895
Subtract 4105 from 4310 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 13:
2050 divided by 821 is 2 with a remainder of 408.
Write down 2 as next digit of the result. 
Result so far: 51140.58952
The remainder is 408 after subtracting 1642 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 14:
When dividing 4080 by 821, we get 4 with a remainder of 796.
Write down 4 as next digit of the result. 
Result so far: 51140.589524
The remainder is 796 after subtracting 3284 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Moving on to step 15:
The number 821 fits into 7960 9 times, leaving a remainder of 571.
The next digit of our result is 9. 
Result so far: 51140.5895249
If we take 7389 away from 7960, we end up with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

On to step 16:
If we divide 5710 by 821, we get 6 and a remainder of 784.
Put 6 as the next digit of the answer. 
Result so far: 51140.58952496
If we subtract 4926 from 5710, we get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

The final result is 51140.58952496 with a remainder of 7.84e-07.
