We're dividing 172955 by 18 
We're looking to find how many times 18 goes into 172955.

Advancing to step 1:
18 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
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 / 18

Let's proceed to step 2:
When dividing 17 by 18, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 18

On to step 3:
172 divided by 18 is 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 9.0
If we take 162 away from 172, we end up with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 18

Moving on to step 4:
18 goes into 109 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Subtracting 108 from 109 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 18

Let's proceed to step 5:
When dividing 15 by 18, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 960.0
Subtract 0 from 15 to get 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 18

On to step 6:
18 can be fit into 155 8 times, resulting in a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 9608.0
If we subtract 144 from 155, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
18 goes into 110 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 9608.6
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
18 can be fit into 20 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 9608.61
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
When dividing 20 by 18, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 9608.611
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 9608.611, with a leftover of 0.0002.
