We look at the division of 8308217 by 321 
We want to divide 8308217 by 321.

Advancing to step 1:
When dividing 8 by 321, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 321

On to step 2:
83 divided by 321 is 0 with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (0) from the dividend, attach it to 83 and continue: 830 / 321

On to step 3:
When dividing 830 by 321, we get 2 with a remainder of 188.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 642 from 830 leaves us with 188.
Take the next digit (8) from the dividend and append it to 188, then repeat: 1888 / 321

Advancing to step 4:
1888 divided by 321 is 5 with a remainder of 283.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 1605 from 1888 to get 283.
Include the next digit (2) from the dividend after 283, then repeat: 2832 / 321

Advancing to step 5:
2832 divided by 321 is 8 with a remainder of 264.
The number 8 becomes the next digit in our result. 
Result so far: 258.0
The remainder is 264 after subtracting 2568 from 2832.
Grab the next digit (1) from the dividend, add it to 264, then carry on: 2641 / 321

Advancing to step 6:
The number 321 fits into 2641 8 times, leaving a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 2588.0
If we subtract 2568 from 2641, we get 73.
Take the next digit (7) from the dividend and append it to 73, then repeat: 737 / 321

Let's proceed to step 7:
737 divided by 321 is 2 with a remainder of 95.
Record the quotient 2 as the next digit in the result. 
Result so far: 25882.0
Subtract 642 from 737 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 8:
When dividing 950 by 321, we get 2 with a remainder of 308.
Put 2 as the next digit of the answer. 
Result so far: 25882.2
If we subtract 642 from 950, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 9:
The number 321 fits into 3080 9 times, leaving a remainder of 191.
Record the quotient 9 as the next digit in the result. 
Result so far: 25882.29
If we take 2889 away from 3080, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 10:
The number 321 fits into 1910 5 times, leaving a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 25882.295
Deduct 1605 from 1910 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 11:
3050 divided by 321 is 9 with a remainder of 161.
Use 9 as the next digit of our solution. 
Result so far: 25882.2959
Subtracting 2889 from 3050 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 12:
The number 321 fits into 1610 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 25882.29595
If we take 1605 away from 1610, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
321 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 25882.29595
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
When dividing 500 by 321, we get 1 with a remainder of 179.
Put 1 as the next digit of the answer. 
Result so far: 25882.2959501
If we subtract 321 from 500, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 15:
321 can be fit into 1790 5 times, resulting in a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 25882.29595015
If we take 1605 away from 1790, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

In conclusion, the division gives 25882.29595015 with a balance of 1.85e-07.
