We look at the division of 15783855 by 317 
We want to divide 15783855 by 317.

On to step 1:
317 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 317

Let's proceed to step 2:
When dividing 15 by 317, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 317

Advancing to step 3:
317 goes into 157 0 times with a remainder of 157.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 157 after subtracting 0 from 157.
Fetch the next digit (8) from the dividend, attach it to 157 and continue: 1578 / 317

Moving on to step 4:
If we divide 1578 by 317, we get 4 and a remainder of 310.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 1268 from 1578, we get 310.
Take the next digit (3) from the dividend and append it to 310, then repeat: 3103 / 317

On to step 5:
The number 317 fits into 3103 9 times, leaving a remainder of 250.
Use 9 as the next digit of our solution. 
Result so far: 49.0
The remainder is 250 after subtracting 2853 from 3103.
Grab the next digit (8) from the dividend, add it to 250, then carry on: 2508 / 317

Step 6:
2508 divided by 317 is 7 with a remainder of 289.
The next digit of our result is 7. 
Result so far: 497.0
The remainder is 289 after subtracting 2219 from 2508.
Include the next digit (5) from the dividend after 289, then repeat: 2895 / 317

Step 7:
2895 divided by 317 is 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 4979.0
Subtracting 2853 from 2895 leaves us with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 317

Moving on to step 8:
425 divided by 317 is 1 with a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 49791.0
If we take 317 away from 425, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 9:
If we divide 1080 by 317, we get 3 and a remainder of 129.
The number 3 becomes the next digit in our result. 
Result so far: 49791.3
Deduct 951 from 1080 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 10:
317 can be fit into 1290 4 times, resulting in a remainder of 22.
The next digit of our result is 4. 
Result so far: 49791.34
If we subtract 1268 from 1290, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
317 goes into 220 0 times with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 49791.34
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 12:
If we divide 2200 by 317, we get 6 and a remainder of 298.
The number 6 becomes the next digit in our result. 
Result so far: 49791.3406
If we take 1902 away from 2200, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 13:
317 goes into 2980 9 times with a remainder of 127.
Use 9 as the next digit of our solution. 
Result so far: 49791.34069
Subtract 2853 from 2980 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 14:
If we divide 1270 by 317, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 49791.340694
The remainder is 2 after subtracting 1268 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 15:
If we divide 20 by 317, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 49791.340694
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 16:
200 divided by 317 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 49791.340694
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 49791.340694 with a remainder of 2e-07.
