We're dividing 432525 by 18 
Let's see how many times 18 fits into 432525.

Let's proceed to step 1:
18 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
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

Advancing to step 2:
If we divide 43 by 18, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 7 after subtracting 36 from 43.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 18

On to step 3:
72 divided by 18 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 72 from 72 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 18

Step 4:
If we divide 5 by 18, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 240.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 18

Step 5:
The number 18 fits into 52 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2402.0
If we subtract 36 from 52, we get 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 18

On to step 6:
The number 18 fits into 165 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 24029.0
Subtract 162 from 165 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
18 goes into 30 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 24029.1
The remainder is 12 after subtracting 18 from 30.
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.
Put 6 as the next digit of the answer. 
Result so far: 24029.16
The remainder is 12 after subtracting 108 from 120.
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 9:
When dividing 120 by 18, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 24029.166
If we take 108 away from 120, we end up 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 24029.166 and a remainder of 0.0012.
