We look at the division of 170492 by 9 
Let's see how many times 9 fits into 170492.

On to step 1:
1 divided by 9 is 0 with 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.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 9

Advancing to step 2:
When dividing 17 by 9, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 9 away from 17, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 9

Moving on to step 3:
The number 9 fits into 80 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 72 from 80 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 9

Let's proceed to step 4:
If we divide 84 by 9, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 189.0
If we take 81 away from 84, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 9

Let's proceed to step 5:
If we divide 39 by 9, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 1894.0
Deduct 36 from 39 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 9

Moving on to step 6:
The number 9 fits into 32 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 18943.0
If we take 27 away from 32, 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.

On to step 7:
If we divide 50 by 9, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 18943.5
If we take 45 away from 50, 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 8:
9 can be fit into 50 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 18943.55
Subtracting 45 from 50 leaves us 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.

The final outcome is 18943.55, with a leftover of 0.005.
