We look at the division of 15909668 by 915 
We're looking to find how many times 915 goes into 15909668.

Moving on to step 1:
If we divide 1 by 915, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 915

Advancing to step 2:
When dividing 15 by 915, 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.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 915

Moving on to step 3:
159 divided by 915 is 0 with a remainder of 159.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 159 and we're left with 159.
Include the next digit (0) from the dividend after 159, then repeat: 1590 / 915

On to step 4:
915 can be fit into 1590 1 times, resulting in a remainder of 675.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 915 from 1590 and we're left with 675.
Include the next digit (9) from the dividend after 675, then repeat: 6759 / 915

Moving on to step 5:
915 goes into 6759 7 times with a remainder of 354.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 6405 from 6759 and we're left with 354.
Grab the next digit (6) from the dividend, add it to 354, then carry on: 3546 / 915

Going ahead to step 6:
If we divide 3546 by 915, we get 3 and a remainder of 801.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
If we take 2745 away from 3546, we end up with 801.
Append the next digit (6) from the dividend to 801 and continue with: 8016 / 915

Moving on to step 7:
When dividing 8016 by 915, we get 8 with a remainder of 696.
Put 8 as the next digit of the answer. 
Result so far: 1738.0
Subtracting 7320 from 8016 leaves us with 696.
Bring next digit (8) of the dividend behind the 696 and repeat the process: 6968 / 915

Going ahead to step 8:
915 goes into 6968 7 times with a remainder of 563.
The number 7 becomes the next digit in our result. 
Result so far: 17387.0
Deduct 6405 from 6968 and we're left with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Advancing to step 9:
The number 915 fits into 5630 6 times, leaving a remainder of 140.
Write down 6 as next digit of the result. 
Result so far: 17387.6
Deduct 5490 from 5630 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
If we divide 1400 by 915, we get 1 and a remainder of 485.
The next digit of our result is 1. 
Result so far: 17387.61
If we subtract 915 from 1400, we get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 11:
The number 915 fits into 4850 5 times, leaving a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 17387.615
Subtract 4575 from 4850 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 12:
If we divide 2750 by 915, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 17387.6153
If we take 2745 away from 2750, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
If we divide 50 by 915, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 17387.6153
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
The number 915 fits into 500 0 times, leaving a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 17387.6153
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 17387.6153 with a remaining 5e-05.
