979642 divided by 25 
The aim is to understand the frequency of 25 in 979642.

Advancing to step 1:
25 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 25

On to step 2:
25 can be fit into 97 3 times, resulting in a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 75 from 97 to get 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 25

Going ahead to step 3:
The number 25 fits into 229 9 times, leaving a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 225 from 229 to get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 25

Moving on to step 4:
When dividing 46 by 25, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 391.0
The remainder is 21 after subtracting 25 from 46.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 25

Step 5:
214 divided by 25 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 3918.0
Subtract 200 from 214 to get 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 25

Going ahead to step 6:
If we divide 142 by 25, we get 5 and a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 39185.0
Subtracting 125 from 142 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
25 goes into 170 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 39185.6
Deduct 150 from 170 and we're left 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.

Advancing to step 8:
25 goes into 200 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 39185.68
If we subtract 200 from 200, 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.

Moving on to step 9:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39185.68
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.

Moving on to step 10:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39185.68
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.

Our division results in 39185.68 with a remaining 0.0.
