449213 ÷ 25 
The aim is to understand the frequency of 25 in 449213.

Let's proceed to step 1:
4 divided by 25 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 25

Let's proceed to step 2:
When dividing 44 by 25, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 25 away from 44, we end up with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 25

Let's proceed to step 3:
If we divide 199 by 25, we get 7 and a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 175 from 199 leaves us with 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 25

Advancing to step 4:
The number 25 fits into 242 9 times, leaving a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 179.0
If we subtract 225 from 242, we get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 25

Moving on to step 5:
If we divide 171 by 25, we get 6 and a remainder of 21.
The next digit of our result is 6. 
Result so far: 1796.0
Subtracting 150 from 171 leaves us with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 25

Advancing to step 6:
If we divide 213 by 25, we get 8 and a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 17968.0
If we subtract 200 from 213, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
25 can be fit into 130 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 17968.5
The remainder is 5 after subtracting 125 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
50 divided by 25 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 17968.52
Deduct 50 from 50 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.

Moving on to step 9:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17968.52
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.

Going ahead to step 10:
0 divided by 25 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17968.52
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.

In conclusion, the division gives 17968.52 with a balance of 0.0.
