We look at the division of 432523 by 18 
Let's see how many times 18 fits into 432523.

Advancing to step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 18

On to step 2:
18 goes into 43 2 times with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 36 from 43 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 18

Step 3:
72 divided by 18 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 72 from 72 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 18

Moving on to step 4:
18 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 240.0
Subtract 0 from 5 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 18

Advancing to step 5:
The number 18 fits into 52 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2402.0
Subtracting 36 from 52 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 18

Moving on to step 6:
18 can be fit into 163 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 24029.0
The remainder is 1 after subtracting 162 from 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 18 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 24029.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 18, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 24029.05
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 18, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 24029.055
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 24029.055, with a leftover of 0.001.
