725107 divided by 18 
We want to divide 725107 by 18.

On to 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
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 18

On to step 2:
The number 18 fits into 72 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 72 from 72 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 18

Going ahead to step 3:
If we divide 5 by 18, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 18

On to step 4:
18 goes into 51 2 times with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 402.0
Deduct 36 from 51 and we're left with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 18

On to step 5:
18 can be fit into 150 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 4028.0
If we subtract 144 from 150, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 18

Let's proceed to step 6:
18 can be fit into 67 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 40283.0
Subtract 54 from 67 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
130 divided by 18 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 40283.7
If we subtract 126 from 130, we 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.

Step 8:
The number 18 fits into 40 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 40283.72
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
18 can be fit into 40 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 40283.722
If we take 36 away from 40, we end up with 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 40283.722, with a leftover of 0.0004.
