Let's divide 485189 by 25
The aim is to understand the frequency of 25 in 485189.

Step 1:
The number 25 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 25

Step 2:
If we divide 48 by 25, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 25 from 48, we get 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 25

Step 3:
25 can be fit into 235 9 times, resulting in a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 10 after subtracting 225 from 235.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 25

Let's proceed to step 4:
The number 25 fits into 101 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 194.0
Subtract 100 from 101 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 25

On to step 5:
25 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 1940.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 25

Going ahead to step 6:
If we divide 189 by 25, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 19407.0
Deduct 175 from 189 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
The number 25 fits into 140 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 19407.5
Deduct 125 from 140 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
25 can be fit into 150 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 19407.56
If we take 150 away from 150, 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.

Going ahead to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19407.56
Deduct 0 from 0 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.

Step 10:
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: 19407.56
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.

Our division results in 19407.56 with a remaining 0.0.
