Let's divide 128731 by 18
We want to figure out the number of times 128731 can be divided by 18.

Moving on to step 1:
If we divide 1 by 18, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 18

Step 2:
18 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 18

Moving on to step 3:
128 divided by 18 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 126 from 128 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 18

Let's proceed to step 4:
18 can be fit into 27 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtract 18 from 27 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 18

On to step 5:
93 divided by 18 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 715.0
If we subtract 90 from 93, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 18

Advancing to step 6:
18 can be fit into 31 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 7151.0
The remainder is 13 after subtracting 18 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 18, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 7151.7
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 18, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 7151.72
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 18, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 7151.722
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 7151.722, with a leftover of 0.0004.
