408740 ÷ 25 
Let's see how many times 25 fits into 408740.

Step 1:
If we divide 4 by 25, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 25

Let's proceed to step 2:
25 goes into 40 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 15 after subtracting 25 from 40.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 25

Step 3:
25 can be fit into 158 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 8 after subtracting 150 from 158.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 25

Moving on to step 4:
If we divide 87 by 25, we get 3 and a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
Subtracting 75 from 87 leaves us with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 25

Advancing to step 5:
25 can be fit into 124 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 1634.0
If we subtract 100 from 124, we get 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 25

Going ahead to step 6:
25 can be fit into 240 9 times, resulting in a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 16349.0
Subtract 225 from 240 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
When dividing 150 by 25, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 16349.6
The remainder is 0 after subtracting 150 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16349.6
Subtract 0 from 0 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.

Let's proceed to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16349.6
If we take 0 away from 0, we end up 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.

After the division, we end up with 16349.6 and a remainder of 0.0.
