We look at the division of 16517681 by 315 
Let's see how many times 315 fits into 16517681.

Advancing to step 1:
The number 315 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 315

Step 2:
When dividing 16 by 315, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 315

Step 3:
If we divide 165 by 315, we get 0 and a remainder of 165.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 165 leaves us with 165.
Append the next digit (1) from the dividend to 165 and continue with: 1651 / 315

On to step 4:
If we divide 1651 by 315, we get 5 and a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 1575 from 1651, we get 76.
Take the next digit (7) from the dividend and append it to 76, then repeat: 767 / 315

On to step 5:
If we divide 767 by 315, we get 2 and a remainder of 137.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we subtract 630 from 767, we get 137.
Fetch the next digit (6) from the dividend, attach it to 137 and continue: 1376 / 315

On to step 6:
The number 315 fits into 1376 4 times, leaving a remainder of 116.
The next digit of our result is 4. 
Result so far: 524.0
The remainder is 116 after subtracting 1260 from 1376.
Append the next digit (8) from the dividend to 116 and continue with: 1168 / 315

On to step 7:
If we divide 1168 by 315, we get 3 and a remainder of 223.
The next digit of our result is 3. 
Result so far: 5243.0
Subtract 945 from 1168 to get 223.
Bring next digit (1) of the dividend behind the 223 and repeat the process: 2231 / 315

On to step 8:
315 can be fit into 2231 7 times, resulting in a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 52437.0
Subtract 2205 from 2231 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
If we divide 260 by 315, we get 0 and a remainder of 260.
The next digit of our result is 0. 
Result so far: 52437.0
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 10:
If we divide 2600 by 315, we get 8 and a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 52437.08
Deduct 2520 from 2600 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
800 divided by 315 is 2 with a remainder of 170.
Put 2 as the next digit of the answer. 
Result so far: 52437.082
Subtracting 630 from 800 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 12:
315 goes into 1700 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 52437.0825
Subtracting 1575 from 1700 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 13:
1250 divided by 315 is 3 with a remainder of 305.
The number 3 becomes the next digit in our result. 
Result so far: 52437.08253
Subtract 945 from 1250 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 14:
3050 divided by 315 is 9 with a remainder of 215.
Write down 9 as next digit of the result. 
Result so far: 52437.082539
Subtract 2835 from 3050 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 15:
When dividing 2150 by 315, we get 6 with a remainder of 260.
Put 6 as the next digit of the answer. 
Result so far: 52437.0825396
If we take 1890 away from 2150, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 16:
If we divide 2600 by 315, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 52437.08253968
If we take 2520 away from 2600, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 52437.08253968, with a leftover of 8e-08.
