15720912 divided by 317 
Our goal is to divide 15720912 by 317.

Advancing to step 1:
When dividing 1 by 317, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 317

Let's proceed to step 2:
317 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 317

Advancing to step 3:
157 divided by 317 is 0 with a remainder of 157.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 157, we end up with 157.
Fetch the next digit (2) from the dividend, attach it to 157 and continue: 1572 / 317

Let's proceed to step 4:
1572 divided by 317 is 4 with a remainder of 304.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1268 from 1572 and we're left with 304.
Bring next digit (0) of the dividend behind the 304 and repeat the process: 3040 / 317

Let's proceed to step 5:
If we divide 3040 by 317, we get 9 and a remainder of 187.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtracting 2853 from 3040 leaves us with 187.
Bring next digit (9) of the dividend behind the 187 and repeat the process: 1879 / 317

Step 6:
If we divide 1879 by 317, we get 5 and a remainder of 294.
Write down 5 as next digit of the result. 
Result so far: 495.0
Subtracting 1585 from 1879 leaves us with 294.
Include the next digit (1) from the dividend after 294, then repeat: 2941 / 317

Step 7:
317 goes into 2941 9 times with a remainder of 88.
Write down 9 as next digit of the result. 
Result so far: 4959.0
Deduct 2853 from 2941 and we're left with 88.
Bring next digit (2) of the dividend behind the 88 and repeat the process: 882 / 317

Step 8:
317 goes into 882 2 times with a remainder of 248.
The next digit of our result is 2. 
Result so far: 49592.0
Deduct 634 from 882 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 9:
317 can be fit into 2480 7 times, resulting in a remainder of 261.
The next digit of our result is 7. 
Result so far: 49592.7
Subtract 2219 from 2480 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Advancing to step 10:
317 can be fit into 2610 8 times, resulting in a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 49592.78
Subtract 2536 from 2610 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 11:
740 divided by 317 is 2 with a remainder of 106.
The next digit of our result is 2. 
Result so far: 49592.782
If we take 634 away from 740, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 12:
317 goes into 1060 3 times with a remainder of 109.
Write down 3 as next digit of the result. 
Result so far: 49592.7823
Subtract 951 from 1060 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 13:
1090 divided by 317 is 3 with a remainder of 139.
The next digit of our result is 3. 
Result so far: 49592.78233
Deduct 951 from 1090 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

The quotient of the division is 49592.78233, and the remainder is 0.000139.
