Let's divide 130431 by 18
Our goal is to divide 130431 by 18.

On to step 1:
1 divided by 18 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 18

Let's proceed to step 2:
18 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 18

Step 3:
If we divide 130 by 18, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 126 away from 130, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 18

On to step 4:
If we divide 44 by 18, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtracting 36 from 44 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 18

Advancing to step 5:
18 goes into 83 4 times with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 724.0
Subtracting 72 from 83 leaves us with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 18

Let's proceed to step 6:
18 goes into 111 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 7246.0
The remainder is 3 after subtracting 108 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
18 can be fit into 30 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 7246.1
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.

Moving on to step 8:
When dividing 120 by 18, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 7246.16
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.

Going ahead to step 9:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 7246.166
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.

Our division results in 7246.166 with a remaining 0.0012.
