8641926 ÷ 321 
We want to figure out the number of times 8641926 can be divided by 321.

Going ahead to step 1:
321 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 321

Let's proceed to step 2:
321 can be fit into 86 0 times, resulting in a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 321

Moving on to step 3:
The number 321 fits into 864 2 times, leaving a remainder of 222.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 642 from 864, we get 222.
Include the next digit (1) from the dividend after 222, then repeat: 2221 / 321

Moving on to step 4:
When dividing 2221 by 321, we get 6 with a remainder of 295.
The next digit of our result is 6. 
Result so far: 26.0
If we subtract 1926 from 2221, we get 295.
Append the next digit (9) from the dividend to 295 and continue with: 2959 / 321

Let's proceed to step 5:
If we divide 2959 by 321, we get 9 and a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 269.0
Subtracting 2889 from 2959 leaves us with 70.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 321

Moving on to step 6:
321 can be fit into 702 2 times, resulting in a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 2692.0
Deduct 642 from 702 and we're left with 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 321

On to step 7:
321 goes into 606 1 times with a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 26921.0
If we subtract 321 from 606, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 8:
321 can be fit into 2850 8 times, resulting in a remainder of 282.
Write down 8 as next digit of the result. 
Result so far: 26921.8
The remainder is 282 after subtracting 2568 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 9:
2820 divided by 321 is 8 with a remainder of 252.
Use 8 as the next digit of our solution. 
Result so far: 26921.88
Subtract 2568 from 2820 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Our division results in 26921.88 with a remaining 0.252.
