We divide 977102 by 25
The aim is to understand the frequency of 25 in 977102.

Step 1:
25 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 25

Going ahead to step 2:
The number 25 fits into 97 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 75 away from 97, we end up with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 25

On to step 3:
If we divide 227 by 25, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we take 225 away from 227, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 25

Let's proceed to step 4:
25 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 390.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 25

Going ahead to step 5:
When dividing 210 by 25, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 3908.0
Subtract 200 from 210 to get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 25

Moving on to step 6:
102 divided by 25 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 39084.0
If we take 100 away from 102, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 25, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 39084.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 25, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 39084.08
Subtracting 200 from 200 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.

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: 39084.08
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.

On to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39084.08
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.

Our division results in 39084.08 with a remaining 0.0.
