We're dividing 17987065 by 915 
We're looking to find how many times 915 goes into 17987065.

Going ahead to step 1:
The number 915 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 915

Moving on to step 2:
The number 915 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 915

On to step 3:
179 divided by 915 is 0 with a remainder of 179.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 179 to get 179.
Fetch the next digit (8) from the dividend, attach it to 179 and continue: 1798 / 915

On to step 4:
The number 915 fits into 1798 1 times, leaving a remainder of 883.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 883 after subtracting 915 from 1798.
Include the next digit (7) from the dividend after 883, then repeat: 8837 / 915

Advancing to step 5:
915 goes into 8837 9 times with a remainder of 602.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 602 after subtracting 8235 from 8837.
Take the next digit (0) from the dividend and append it to 602, then repeat: 6020 / 915

Moving on to step 6:
915 goes into 6020 6 times with a remainder of 530.
Put 6 as the next digit of the answer. 
Result so far: 196.0
Subtract 5490 from 6020 to get 530.
Fetch the next digit (6) from the dividend, attach it to 530 and continue: 5306 / 915

Step 7:
5306 divided by 915 is 5 with a remainder of 731.
The number 5 becomes the next digit in our result. 
Result so far: 1965.0
Subtract 4575 from 5306 to get 731.
Bring next digit (5) of the dividend behind the 731 and repeat the process: 7315 / 915

Going ahead to step 8:
7315 divided by 915 is 7 with a remainder of 910.
Record the quotient 7 as the next digit in the result. 
Result so far: 19657.0
If we subtract 6405 from 7315, we get 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

On to step 9:
915 can be fit into 9100 9 times, resulting in a remainder of 865.
Put 9 as the next digit of the answer. 
Result so far: 19657.9
If we take 8235 away from 9100, we end up with 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Advancing to step 10:
The number 915 fits into 8650 9 times, leaving a remainder of 415.
Use 9 as the next digit of our solution. 
Result so far: 19657.99
If we take 8235 away from 8650, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

After the division, we end up with 19657.99 and a remainder of 0.415.
