725470 divided by 18 
We want to figure out the number of times 725470 can be divided by 18.

Let's proceed to step 1:
7 divided by 18 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 18

Advancing to step 2:
72 divided by 18 is 4 with 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.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 18

Step 3:
The number 18 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 18

Let's proceed to step 4:
When dividing 54 by 18, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
If we subtract 54 from 54, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 18

On to step 5:
The number 18 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 4030.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 18

Moving on to step 6:
If we divide 70 by 18, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 40303.0
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
When dividing 160 by 18, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 40303.8
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 40303.88
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 40303.88 with a remaining 0.016.
