977185 ÷ 25 
The aim is to understand the frequency of 25 in 977185.

Step 1:
When dividing 9 by 25, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 25

Going ahead to step 2:
If we divide 97 by 25, we get 3 and a remainder of 22.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 75 from 97 to get 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 25

On to step 3:
The number 25 fits into 227 9 times, leaving a remainder of 2.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 2 after subtracting 225 from 227.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 25

Going ahead to step 4:
21 divided by 25 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 390.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 25

Going ahead to step 5:
25 can be fit into 218 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 3908.0
If we take 200 away from 218, we end up with 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 25

On to step 6:
185 divided by 25 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 39087.0
Subtracting 175 from 185 leaves us 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.

Moving on to step 7:
25 goes into 100 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 39087.4
Subtracting 100 from 100 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 8:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39087.4
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.

Moving on to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39087.4
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.

The quotient of the division is 39087.4, and the remainder is 0.0.
