464581 divided by 25 
The aim is to understand the frequency of 25 in 464581.

Step 1:
4 divided by 25 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 25

Step 2:
If we divide 46 by 25, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 25 away from 46, we end up with 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 25

Going ahead to step 3:
The number 25 fits into 214 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 200 away from 214, we end up with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 25

Moving on to step 4:
145 divided by 25 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Subtracting 125 from 145 leaves us with 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 25

Going ahead to step 5:
25 goes into 208 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 1858.0
Deduct 200 from 208 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 25

Moving on to step 6:
The number 25 fits into 81 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 18583.0
Subtracting 75 from 81 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
If we divide 60 by 25, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 18583.2
Deduct 50 from 60 and we're left 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.

Let's proceed to step 8:
The number 25 fits into 100 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 18583.24
The remainder is 0 after subtracting 100 from 100.
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:
0 divided by 25 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18583.24
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.

Going ahead to step 10:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18583.24
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.

Our division results in 18583.24 with a remaining 0.0.
