We look at the division of 429726 by 18 
We're looking to find how many times 18 goes into 429726.

Let's proceed to step 1:
When dividing 4 by 18, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 18

Step 2:
The number 18 fits into 42 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 6 after subtracting 36 from 42.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 18

Moving on to step 3:
When dividing 69 by 18, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 54 from 69 leaves us with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 18

Moving on to step 4:
The number 18 fits into 157 8 times, leaving a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 238.0
If we take 144 away from 157, we end up with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 18

Advancing to step 5:
The number 18 fits into 132 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 2387.0
Subtracting 126 from 132 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 18

Let's proceed to step 6:
The number 18 fits into 66 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 23873.0
Subtracting 54 from 66 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
If we divide 120 by 18, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 23873.6
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
18 goes into 120 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 23873.66
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 23873.66 and a remainder of 0.012.
