321945 ÷ 39 
We're looking to find how many times 39 goes into 321945.

Advancing to step 1:
3 divided by 39 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 39

Moving on to step 2:
39 goes into 32 0 times with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 39

Moving on to step 3:
321 divided by 39 is 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 312 away from 321, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 39

Moving on to step 4:
39 can be fit into 99 2 times, resulting in a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 82.0
The remainder is 21 after subtracting 78 from 99.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 39

Let's proceed to step 5:
When dividing 214 by 39, we get 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 825.0
If we subtract 195 from 214, we get 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 39

Advancing to step 6:
39 goes into 195 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 8255.0
Subtracting 195 from 195 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
If we divide 0 by 39, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8255.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
When dividing 0 by 39, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8255.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 8255.0 with a balance of 0.0.
