We look at the division of 173042 by 9 
We want to divide 173042 by 9.

Let's proceed to step 1:
If we divide 1 by 9, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 9

Advancing to step 2:
If we divide 17 by 9, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we take 9 away from 17, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 9

Let's proceed to step 3:
If we divide 83 by 9, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 2 after subtracting 81 from 83.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 9

Going ahead to step 4:
20 divided by 9 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 192.0
If we take 18 away from 20, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 9

Let's proceed to step 5:
When dividing 24 by 9, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 1922.0
If we take 18 away from 24, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 9

Step 6:
When dividing 62 by 9, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 19226.0
If we subtract 54 from 62, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
9 can be fit into 80 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 19226.8
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 9, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 19226.88
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 19226.88 with a balance of 0.008.
