453718 divided by 25 
The aim is to understand the frequency of 25 in 453718.

Moving on to step 1:
25 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 25

On to step 2:
25 can be fit into 45 1 times, resulting in a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 25 from 45 and we're left with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 25

Step 3:
If we divide 203 by 25, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 200 from 203 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 25

On to step 4:
25 goes into 37 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 181.0
If we subtract 25 from 37, we get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 25

Step 5:
The number 25 fits into 121 4 times, leaving a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 1814.0
If we take 100 away from 121, we end up with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 25

Going ahead to step 6:
If we divide 218 by 25, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 18148.0
If we subtract 200 from 218, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
When dividing 180 by 25, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 18148.7
Deduct 175 from 180 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
If we divide 50 by 25, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 18148.72
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.

Let's proceed to step 9:
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: 18148.72
If we take 0 away from 0, 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.

Let's proceed to step 10:
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: 18148.72
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 18148.72 with a remainder of 0.0.
