82090842 ÷ 621 
We want to divide 82090842 by 621.

On to step 1:
When dividing 8 by 621, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 621

Going ahead to step 2:
82 divided by 621 is 0 with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Fetch the next digit (0) from the dividend, attach it to 82 and continue: 820 / 621

Step 3:
When dividing 820 by 621, we get 1 with a remainder of 199.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 621 from 820 to get 199.
Append the next digit (9) from the dividend to 199 and continue with: 1999 / 621

Let's proceed to step 4:
When dividing 1999 by 621, we get 3 with a remainder of 136.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 136 after subtracting 1863 from 1999.
Append the next digit (0) from the dividend to 136 and continue with: 1360 / 621

On to step 5:
If we divide 1360 by 621, we get 2 and a remainder of 118.
Write down 2 as next digit of the result. 
Result so far: 132.0
Subtract 1242 from 1360 to get 118.
Include the next digit (8) from the dividend after 118, then repeat: 1188 / 621

Moving on to step 6:
The number 621 fits into 1188 1 times, leaving a remainder of 567.
The next digit of our result is 1. 
Result so far: 1321.0
The remainder is 567 after subtracting 621 from 1188.
Bring next digit (4) of the dividend behind the 567 and repeat the process: 5674 / 621

Going ahead to step 7:
621 goes into 5674 9 times with a remainder of 85.
Write down 9 as next digit of the result. 
Result so far: 13219.0
Subtract 5589 from 5674 to get 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 621

On to step 8:
852 divided by 621 is 1 with a remainder of 231.
The number 1 becomes the next digit in our result. 
Result so far: 132191.0
If we take 621 away from 852, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 9:
621 can be fit into 2310 3 times, resulting in a remainder of 447.
Write down 3 as next digit of the result. 
Result so far: 132191.3
Subtract 1863 from 2310 to get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

On to step 10:
4470 divided by 621 is 7 with a remainder of 123.
The number 7 becomes the next digit in our result. 
Result so far: 132191.37
Deduct 4347 from 4470 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 11:
621 goes into 1230 1 times with a remainder of 609.
The next digit of our result is 1. 
Result so far: 132191.371
The remainder is 609 after subtracting 621 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Moving on to step 12:
If we divide 6090 by 621, we get 9 and a remainder of 501.
The number 9 becomes the next digit in our result. 
Result so far: 132191.3719
If we take 5589 away from 6090, we end up with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Moving on to step 13:
5010 divided by 621 is 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 132191.37198
Subtracting 4968 from 5010 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
When dividing 420 by 621, we get 0 with a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 132191.37198
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 15:
621 goes into 4200 6 times with a remainder of 474.
The number 6 becomes the next digit in our result. 
Result so far: 132191.3719806
The remainder is 474 after subtracting 3726 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 16:
621 goes into 4740 7 times with a remainder of 393.
Record the quotient 7 as the next digit in the result. 
Result so far: 132191.37198067
The remainder is 393 after subtracting 4347 from 4740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Our division results in 132191.37198067 with a remaining 3.93e-07.
