Let's see how many times 321 fits into 39064790.

Going ahead to step 1:
321 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
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 321

Advancing to step 2:
39 divided by 321 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 321

Step 3:
321 can be fit into 390 1 times, resulting in a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 321 from 390 to get 69.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 321

On to step 4:
696 divided by 321 is 2 with a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 642 away from 696, we end up with 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 321

Moving on to step 5:
544 divided by 321 is 1 with a remainder of 223.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
If we subtract 321 from 544, we get 223.
Fetch the next digit (7) from the dividend, attach it to 223 and continue: 2237 / 321

Moving on to step 6:
The number 321 fits into 2237 6 times, leaving a remainder of 311.
Use 6 as the next digit of our solution. 
Result so far: 1216.0
Subtracting 1926 from 2237 leaves us with 311.
Take the next digit (9) from the dividend and append it to 311, then repeat: 3119 / 321

Moving on to step 7:
The number 321 fits into 3119 9 times, leaving a remainder of 230.
Write down 9 as next digit of the result. 
Result so far: 12169.0
The remainder is 230 after subtracting 2889 from 3119.
Grab the next digit (0) from the dividend, add it to 230, then carry on: 2300 / 321

On to step 8:
The number 321 fits into 2300 7 times, leaving a remainder of 53.
The next digit of our result is 7. 
Result so far: 121697.0
If we take 2247 away from 2300, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
321 can be fit into 530 1 times, resulting in a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 121697.1
The remainder is 209 after subtracting 321 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 10:
The number 321 fits into 2090 6 times, leaving a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 121697.16
If we take 1926 away from 2090, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 11:
If we divide 1640 by 321, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 121697.165
Subtracting 1605 from 1640 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
If we divide 350 by 321, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 121697.1651
If we take 321 away from 350, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
321 goes into 290 0 times with a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 121697.1651
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 14:
The number 321 fits into 2900 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 121697.165109
The remainder is 11 after subtracting 2889 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 15:
321 can be fit into 110 0 times, resulting in a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 121697.165109
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 16:
321 goes into 1100 3 times with a remainder of 137.
Write down 3 as next digit of the result. 
Result so far: 121697.16510903
Deduct 963 from 1100 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

The final outcome is 121697.16510903, with a leftover of 1.37e-07.
