430135 ÷ 18 
We want to divide 430135 by 18.

Let's proceed to step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 18

Advancing to step 2:
18 can be fit into 43 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
If we take 36 away from 43, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 18

Let's proceed to step 3:
When dividing 70 by 18, we get 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 54 from 70 to get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 18

Going ahead to step 4:
161 divided by 18 is 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
Subtract 144 from 161 to get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 18

On to step 5:
18 can be fit into 173 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 2389.0
If we subtract 162 from 173, we get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 18

Advancing to step 6:
18 goes into 115 6 times with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 23896.0
Subtracting 108 from 115 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 18 is 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 23896.3
If we take 54 away from 70, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 23896.38
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 23896.388
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 23896.388, with a leftover of 0.0016.
