We look at the division of 25845462 by 454 
The aim is to understand the frequency of 454 in 25845462.

Moving on to step 1:
2 divided by 454 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 454

Moving on to step 2:
If we divide 25 by 454, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 454

Advancing to step 3:
If we divide 258 by 454, we get 0 and a remainder of 258.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 258 and we're left with 258.
Bring next digit (4) of the dividend behind the 258 and repeat the process: 2584 / 454

Moving on to step 4:
454 can be fit into 2584 5 times, resulting in a remainder of 314.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 2270 from 2584, we get 314.
Grab the next digit (5) from the dividend, add it to 314, then carry on: 3145 / 454

Let's proceed to step 5:
3145 divided by 454 is 6 with a remainder of 421.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Subtracting 2724 from 3145 leaves us with 421.
Append the next digit (4) from the dividend to 421 and continue with: 4214 / 454

Step 6:
4214 divided by 454 is 9 with a remainder of 128.
Record the quotient 9 as the next digit in the result. 
Result so far: 569.0
If we subtract 4086 from 4214, we get 128.
Take the next digit (6) from the dividend and append it to 128, then repeat: 1286 / 454

Advancing to step 7:
1286 divided by 454 is 2 with a remainder of 378.
The next digit of our result is 2. 
Result so far: 5692.0
Subtracting 908 from 1286 leaves us with 378.
Append the next digit (2) from the dividend to 378 and continue with: 3782 / 454

Advancing to step 8:
When dividing 3782 by 454, we get 8 with a remainder of 150.
Write down 8 as next digit of the result. 
Result so far: 56928.0
Subtracting 3632 from 3782 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 9:
1500 divided by 454 is 3 with a remainder of 138.
Use 3 as the next digit of our solution. 
Result so far: 56928.3
Subtracting 1362 from 1500 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 10:
454 can be fit into 1380 3 times, resulting in a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 56928.33
If we take 1362 away from 1380, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 56928.33 with a balance of 0.018.
