429173 ÷ 18 
We want to divide 429173 by 18.

Let's proceed to step 1:
The number 18 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 18

Advancing to step 2:
When dividing 42 by 18, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 36 from 42 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 18

Step 3:
69 divided by 18 is 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 54 from 69 to get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 18

Let's proceed to step 4:
When dividing 151 by 18, we get 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 238.0
The remainder is 7 after subtracting 144 from 151.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 18

Moving on to step 5:
If we divide 77 by 18, we get 4 and a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 2384.0
If we take 72 away from 77, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 18

Let's proceed to step 6:
53 divided by 18 is 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 23842.0
Deduct 36 from 53 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
170 divided by 18 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 23842.9
Subtract 162 from 170 to 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.

Step 8:
The number 18 fits into 80 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 23842.94
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.

Going ahead to step 9:
When dividing 80 by 18, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 23842.944
If we subtract 72 from 80, 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.

In conclusion, the division gives 23842.944 with a balance of 0.0008.
