We divide 407431 by 18
Our goal is to divide 407431 by 18.

Advancing to step 1:
18 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 18

Let's proceed to step 2:
40 divided by 18 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 36 from 40 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 18

Going ahead to step 3:
If we divide 47 by 18, we get 2 and a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 36 away from 47, we end up with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 18

Step 4:
18 can be fit into 114 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
If we take 108 away from 114, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 18

Advancing to step 5:
18 can be fit into 63 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 2263.0
Subtract 54 from 63 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 18

Let's proceed to step 6:
If we divide 91 by 18, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 22635.0
If we subtract 90 from 91, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
18 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 22635.0
If we take 0 away from 10, we end up 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.

Going ahead to step 8:
100 divided by 18 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 22635.05
If we take 90 away from 100, we end up 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.

On to step 9:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 22635.055
If we subtract 90 from 100, we 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.

Our division results in 22635.055 with a remaining 0.001.
