25897468 ÷ 400 
The aim is to understand the frequency of 400 in 25897468.

Moving on to step 1:
400 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 400

Let's proceed to step 2:
400 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 400

Step 3:
258 divided by 400 is 0 with a remainder of 258.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 258, we get 258.
Include the next digit (9) from the dividend after 258, then repeat: 2589 / 400

Let's proceed to step 4:
400 goes into 2589 6 times with a remainder of 189.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 2400 from 2589 and we're left with 189.
Fetch the next digit (7) from the dividend, attach it to 189 and continue: 1897 / 400

Going ahead to step 5:
If we divide 1897 by 400, we get 4 and a remainder of 297.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 297 after subtracting 1600 from 1897.
Append the next digit (4) from the dividend to 297 and continue with: 2974 / 400

Moving on to step 6:
2974 divided by 400 is 7 with a remainder of 174.
The number 7 becomes the next digit in our result. 
Result so far: 647.0
The remainder is 174 after subtracting 2800 from 2974.
Append the next digit (6) from the dividend to 174 and continue with: 1746 / 400

Going ahead to step 7:
400 goes into 1746 4 times with a remainder of 146.
Record the quotient 4 as the next digit in the result. 
Result so far: 6474.0
The remainder is 146 after subtracting 1600 from 1746.
Fetch the next digit (8) from the dividend, attach it to 146 and continue: 1468 / 400

Moving on to step 8:
400 goes into 1468 3 times with a remainder of 268.
Put 3 as the next digit of the answer. 
Result so far: 64743.0
Subtracting 1200 from 1468 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 9:
If we divide 2680 by 400, we get 6 and a remainder of 280.
The next digit of our result is 6. 
Result so far: 64743.6
Subtracting 2400 from 2680 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 10:
When dividing 2800 by 400, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 64743.67
Subtracting 2800 from 2800 leaves us 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.

Going ahead to step 11:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 64743.67
Subtracting 0 from 0 leaves us 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.

On to step 12:
When dividing 0 by 400, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 64743.67
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 64743.67 with a remainder of 0.0.
