We're dividing 39309952 by 317 
Our goal is to divide 39309952 by 317.

Step 1:
The number 317 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 317

Step 2:
39 divided by 317 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 317

Let's proceed to step 3:
393 divided by 317 is 1 with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 317 from 393 to get 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 317

Let's proceed to step 4:
760 divided by 317 is 2 with a remainder of 126.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 634 from 760 and we're left with 126.
Take the next digit (9) from the dividend and append it to 126, then repeat: 1269 / 317

Advancing to step 5:
If we divide 1269 by 317, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 124.0
The remainder is 1 after subtracting 1268 from 1269.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 317

On to step 6:
317 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 1240.0
Subtract 0 from 19 to get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 317

Step 7:
317 can be fit into 195 0 times, resulting in a remainder of 195.
Use 0 as the next digit of our solution. 
Result so far: 12400.0
The remainder is 195 after subtracting 0 from 195.
Append the next digit (2) from the dividend to 195 and continue with: 1952 / 317

Advancing to step 8:
When dividing 1952 by 317, we get 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 124006.0
If we take 1902 away from 1952, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
317 can be fit into 500 1 times, resulting in a remainder of 183.
Record the quotient 1 as the next digit in the result. 
Result so far: 124006.1
Subtracting 317 from 500 leaves us with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 10:
1830 divided by 317 is 5 with a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 124006.15
The remainder is 245 after subtracting 1585 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 11:
If we divide 2450 by 317, we get 7 and a remainder of 231.
The number 7 becomes the next digit in our result. 
Result so far: 124006.157
If we take 2219 away from 2450, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 12:
317 can be fit into 2310 7 times, resulting in a remainder of 91.
Use 7 as the next digit of our solution. 
Result so far: 124006.1577
The remainder is 91 after subtracting 2219 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Our division results in 124006.1577 with a remaining 0.00091.
