8220238 ÷ 621 
We want to figure out the number of times 8220238 can be divided by 621.

Going ahead to step 1:
621 can be fit into 8 0 times, resulting in 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.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 621

Step 2:
82 divided by 621 is 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Include the next digit (2) from the dividend after 82, then repeat: 822 / 621

On to step 3:
822 divided by 621 is 1 with a remainder of 201.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 621 from 822 to get 201.
Include the next digit (0) from the dividend after 201, then repeat: 2010 / 621

Going ahead to step 4:
2010 divided by 621 is 3 with a remainder of 147.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 147 after subtracting 1863 from 2010.
Bring next digit (2) of the dividend behind the 147 and repeat the process: 1472 / 621

Advancing to step 5:
When dividing 1472 by 621, we get 2 with a remainder of 230.
Write down 2 as next digit of the result. 
Result so far: 132.0
Subtract 1242 from 1472 to get 230.
Include the next digit (3) from the dividend after 230, then repeat: 2303 / 621

Let's proceed to step 6:
621 goes into 2303 3 times with a remainder of 440.
The next digit of our result is 3. 
Result so far: 1323.0
The remainder is 440 after subtracting 1863 from 2303.
Fetch the next digit (8) from the dividend, attach it to 440 and continue: 4408 / 621

On to step 7:
621 goes into 4408 7 times with a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 13237.0
Subtracting 4347 from 4408 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 8:
610 divided by 621 is 0 with a remainder of 610.
The number 0 becomes the next digit in our result. 
Result so far: 13237.0
Deduct 0 from 610 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 9:
621 goes into 6100 9 times with a remainder of 511.
The next digit of our result is 9. 
Result so far: 13237.09
Subtracting 5589 from 6100 leaves us with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

On to step 10:
621 goes into 5110 8 times with a remainder of 142.
Record the quotient 8 as the next digit in the result. 
Result so far: 13237.098
If we subtract 4968 from 5110, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 11:
When dividing 1420 by 621, we get 2 with a remainder of 178.
Write down 2 as next digit of the result. 
Result so far: 13237.0982
Subtract 1242 from 1420 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 12:
621 goes into 1780 2 times with a remainder of 538.
Write down 2 as next digit of the result. 
Result so far: 13237.09822
If we subtract 1242 from 1780, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The final result is 13237.09822 with a remainder of 0.000538.
