We're dividing 39369388 by 313 
We want to figure out the number of times 39369388 can be divided by 313.

On to step 1:
313 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 313

On to step 2:
If we divide 39 by 313, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 313

Moving on to step 3:
If we divide 393 by 313, we get 1 and a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 313 from 393 to get 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 313

On to step 4:
313 can be fit into 806 2 times, resulting in a remainder of 180.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 180 after subtracting 626 from 806.
Bring next digit (9) of the dividend behind the 180 and repeat the process: 1809 / 313

On to step 5:
The number 313 fits into 1809 5 times, leaving a remainder of 244.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Deduct 1565 from 1809 and we're left with 244.
Bring next digit (3) of the dividend behind the 244 and repeat the process: 2443 / 313

On to step 6:
313 goes into 2443 7 times with a remainder of 252.
Put 7 as the next digit of the answer. 
Result so far: 1257.0
Subtracting 2191 from 2443 leaves us with 252.
Append the next digit (8) from the dividend to 252 and continue with: 2528 / 313

Step 7:
2528 divided by 313 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 12578.0
Subtract 2504 from 2528 to get 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 313

Advancing to step 8:
When dividing 248 by 313, we get 0 with a remainder of 248.
The next digit of our result is 0. 
Result so far: 125780.0
If we subtract 0 from 248, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 9:
The number 313 fits into 2480 7 times, leaving a remainder of 289.
The next digit of our result is 7. 
Result so far: 125780.7
If we take 2191 away from 2480, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 10:
The number 313 fits into 2890 9 times, leaving a remainder of 73.
Record the quotient 9 as the next digit in the result. 
Result so far: 125780.79
If we take 2817 away from 2890, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 11:
730 divided by 313 is 2 with a remainder of 104.
Write down 2 as next digit of the result. 
Result so far: 125780.792
The remainder is 104 after subtracting 626 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
313 can be fit into 1040 3 times, resulting in a remainder of 101.
The next digit of our result is 3. 
Result so far: 125780.7923
Subtract 939 from 1040 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 13:
When dividing 1010 by 313, we get 3 with a remainder of 71.
Write down 3 as next digit of the result. 
Result so far: 125780.79233
Subtract 939 from 1010 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final result is 125780.79233 with a remainder of 7.1e-05.
