We look at the division of 17517274 by 863 
We want to figure out the number of times 17517274 can be divided by 863.

Let's proceed to step 1:
863 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 863

Advancing to step 2:
17 divided by 863 is 0 with 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.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 863

Moving on to step 3:
If we divide 175 by 863, we get 0 and a remainder of 175.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 175 after subtracting 0 from 175.
Fetch the next digit (1) from the dividend, attach it to 175 and continue: 1751 / 863

Moving on to step 4:
If we divide 1751 by 863, we get 2 and a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1726 away from 1751, we end up with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 863

Advancing to step 5:
863 can be fit into 257 0 times, resulting in a remainder of 257.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 257, we end up with 257.
Grab the next digit (2) from the dividend, add it to 257, then carry on: 2572 / 863

On to step 6:
The number 863 fits into 2572 2 times, leaving a remainder of 846.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
Subtracting 1726 from 2572 leaves us with 846.
Fetch the next digit (7) from the dividend, attach it to 846 and continue: 8467 / 863

Let's proceed to step 7:
If we divide 8467 by 863, we get 9 and a remainder of 700.
Write down 9 as next digit of the result. 
Result so far: 2029.0
If we subtract 7767 from 8467, we get 700.
Take the next digit (4) from the dividend and append it to 700, then repeat: 7004 / 863

Moving on to step 8:
When dividing 7004 by 863, we get 8 with a remainder of 100.
The next digit of our result is 8. 
Result so far: 20298.0
Subtracting 6904 from 7004 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 9:
When dividing 1000 by 863, we get 1 with a remainder of 137.
The next digit of our result is 1. 
Result so far: 20298.1
The remainder is 137 after subtracting 863 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 10:
863 goes into 1370 1 times with a remainder of 507.
Record the quotient 1 as the next digit in the result. 
Result so far: 20298.11
Deduct 863 from 1370 and we're left with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

The final outcome is 20298.11, with a leftover of 0.507.
