Let's divide 321330 by 39
We want to figure out the number of times 321330 can be divided by 39.

Step 1:
39 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 39

Step 2:
The number 39 fits into 32 0 times, leaving a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 39

Let's proceed to step 3:
39 goes into 321 8 times with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 312 from 321 leaves us with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 39

Going ahead to step 4:
39 goes into 93 2 times with a remainder of 15.
The next digit of our result is 2. 
Result so far: 82.0
Subtracting 78 from 93 leaves us with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 39

Step 5:
The number 39 fits into 153 3 times, leaving a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 823.0
The remainder is 36 after subtracting 117 from 153.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 39

Let's proceed to step 6:
360 divided by 39 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 8239.0
If we subtract 351 from 360, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
39 can be fit into 90 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 8239.2
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 39, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 8239.23
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 8239.23
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 39, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 8239.2307
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
If we divide 270 by 39, we get 6 and a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 8239.23076
Subtract 234 from 270 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
39 goes into 360 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 8239.230769
If we take 351 away from 360, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
The number 39 fits into 90 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 8239.2307692
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
When dividing 120 by 39, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 8239.23076923
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 8239.23076923 with a balance of 3e-09.
