55221350 divided by 25 
The aim is to understand the frequency of 25 in 55221350.

Going ahead to step 1:
25 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 25

Let's proceed to step 2:
25 can be fit into 55 2 times, resulting in a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 50 from 55 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 25

Let's proceed to step 3:
When dividing 52 by 25, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 50 from 52, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 25

Step 4:
If we divide 22 by 25, we get 0 and a remainder of 22.
The next digit of our result is 0. 
Result so far: 220.0
If we subtract 0 from 22, we get 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 25

Let's proceed to step 5:
When dividing 221 by 25, we get 8 with a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 2208.0
Subtracting 200 from 221 leaves us with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 25

Going ahead to step 6:
When dividing 213 by 25, we get 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 22088.0
Deduct 200 from 213 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 25

Moving on to step 7:
135 divided by 25 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 220885.0
The remainder is 10 after subtracting 125 from 135.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 25

Moving on to step 8:
If we divide 100 by 25, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 2208854.0
If we take 100 away from 100, 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.

Moving on to step 9:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2208854.0
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.

Going ahead to 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: 2208854.0
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.

After the division, we end up with 2208854.0 and a remainder of 0.0.
