431337 ÷ 18 
We want to divide 431337 by 18.

Let's proceed to step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 18

Going ahead to step 2:
The number 18 fits into 43 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 36 from 43, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 18

Advancing to step 3:
The number 18 fits into 71 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 54 from 71 leaves us with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 18

Moving on to step 4:
18 can be fit into 173 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 239.0
Subtracting 162 from 173 leaves us with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 18

Let's proceed to step 5:
If we divide 113 by 18, we get 6 and a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 2396.0
The remainder is 5 after subtracting 108 from 113.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 18

Let's proceed to step 6:
18 can be fit into 57 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 23963.0
Deduct 54 from 57 and we're left with 3.
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:
When dividing 30 by 18, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 23963.1
If we take 18 away from 30, 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.

Moving on to step 8:
When dividing 120 by 18, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 23963.16
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.

On to step 9:
When dividing 120 by 18, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 23963.166
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.

The final result is 23963.166 with a remainder of 0.0012.
