We're dividing 318405 by 25 
Let's see how many times 25 fits into 318405.

Let's proceed to step 1:
25 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 25

Advancing to step 2:
The number 25 fits into 31 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 25 from 31 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 25

Step 3:
The number 25 fits into 68 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 50 from 68 to get 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 25

Step 4:
25 goes into 184 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 175 from 184, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 25

Advancing to step 5:
If we divide 90 by 25, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 1273.0
The remainder is 15 after subtracting 75 from 90.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 25

Let's proceed to step 6:
25 goes into 155 6 times with a remainder of 5.
The next digit of our result is 6. 
Result so far: 12736.0
Subtracting 150 from 155 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
When dividing 50 by 25, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 12736.2
Subtract 50 from 50 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12736.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
25 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12736.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 12736.2 with a balance of 0.0.
