17398215 ÷ 915 
We want to divide 17398215 by 915.

Advancing to step 1:
915 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 915

Let's proceed to step 2:
When dividing 17 by 915, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 915

On to step 3:
173 divided by 915 is 0 with a remainder of 173.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 173, we get 173.
Append the next digit (9) from the dividend to 173 and continue with: 1739 / 915

Moving on to step 4:
915 can be fit into 1739 1 times, resulting in a remainder of 824.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 915 from 1739 and we're left with 824.
Append the next digit (8) from the dividend to 824 and continue with: 8248 / 915

Let's proceed to step 5:
915 goes into 8248 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 8235 away from 8248, we end up with 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 915

On to step 6:
915 can be fit into 132 0 times, resulting in a remainder of 132.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Deduct 0 from 132 and we're left with 132.
Append the next digit (1) from the dividend to 132 and continue with: 1321 / 915

On to step 7:
915 goes into 1321 1 times with a remainder of 406.
The number 1 becomes the next digit in our result. 
Result so far: 1901.0
Subtract 915 from 1321 to get 406.
Bring next digit (5) of the dividend behind the 406 and repeat the process: 4065 / 915

Advancing to step 8:
If we divide 4065 by 915, we get 4 and a remainder of 405.
Write down 4 as next digit of the result. 
Result so far: 19014.0
Subtracting 3660 from 4065 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Moving on to step 9:
915 can be fit into 4050 4 times, resulting in a remainder of 390.
Use 4 as the next digit of our solution. 
Result so far: 19014.4
If we take 3660 away from 4050, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
3900 divided by 915 is 4 with a remainder of 240.
The next digit of our result is 4. 
Result so far: 19014.44
Subtract 3660 from 3900 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 19014.44 and a remainder of 0.24.
