We're dividing 731712 by 18 
We want to figure out the number of times 731712 can be divided by 18.

Step 1:
The number 18 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 18

Advancing to step 2:
The number 18 fits into 73 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 72 from 73 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 18

Moving on to step 3:
11 divided by 18 is 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 11 to get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 18

Step 4:
If we divide 117 by 18, we get 6 and a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 406.0
Deduct 108 from 117 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 18

Going ahead to step 5:
If we divide 91 by 18, we get 5 and a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 4065.0
If we subtract 90 from 91, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 18

On to step 6:
18 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 40650.0
Subtract 0 from 12 to 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.

Going ahead to step 7:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 40650.6
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.

Step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 40650.66
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.

In conclusion, the division gives 40650.66 with a balance of 0.012.
