We divide 400456 by 25
The aim is to understand the frequency of 25 in 400456.

Let's proceed to step 1:
The number 25 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 25

Step 2:
25 can be fit into 40 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 25 from 40 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 25

On to step 3:
25 can be fit into 150 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 150 from 150 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 25

Step 4:
If we divide 4 by 25, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 160.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 25

Going ahead to step 5:
If we divide 45 by 25, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1601.0
Subtract 25 from 45 to get 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 25

Going ahead to step 6:
206 divided by 25 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 16018.0
If we subtract 200 from 206, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 25, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 16018.2
If we take 50 away from 60, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 25, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 16018.24
If we subtract 100 from 100, 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.

Moving on to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16018.24
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16018.24
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.

The final result is 16018.24 with a remainder of 0.0.
