Let's divide 726789 by 18
Our goal is to divide 726789 by 18.

Advancing to step 1:
18 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 18

Let's proceed to step 2:
18 can be fit into 72 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 72 from 72, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 18

On to step 3:
If we divide 6 by 18, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 6, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 18

On to step 4:
If we divide 67 by 18, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
If we subtract 54 from 67, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 18

Let's proceed to step 5:
The number 18 fits into 138 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 4037.0
Deduct 126 from 138 and we're left with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 18

Let's proceed to step 6:
When dividing 129 by 18, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 40377.0
The remainder is 3 after subtracting 126 from 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 18, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 40377.1
Subtracting 18 from 30 leaves us 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:
18 can be fit into 120 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 40377.16
Subtract 108 from 120 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.

Step 9:
18 goes into 120 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 40377.166
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 40377.166 with a remainder of 0.0012.
