25935966 divided by 975 
The aim is to understand the frequency of 975 in 25935966.

Going ahead to step 1:
2 divided by 975 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 975

On to step 2:
975 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 975

On to step 3:
259 divided by 975 is 0 with a remainder of 259.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 259 after subtracting 0 from 259.
Grab the next digit (3) from the dividend, add it to 259, then carry on: 2593 / 975

Step 4:
When dividing 2593 by 975, we get 2 with a remainder of 643.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1950 from 2593 leaves us with 643.
Fetch the next digit (5) from the dividend, attach it to 643 and continue: 6435 / 975

On to step 5:
The number 975 fits into 6435 6 times, leaving a remainder of 585.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 5850 away from 6435, we end up with 585.
Append the next digit (9) from the dividend to 585 and continue with: 5859 / 975

Moving on to step 6:
975 goes into 5859 6 times with a remainder of 9.
The next digit of our result is 6. 
Result so far: 266.0
The remainder is 9 after subtracting 5850 from 5859.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 975

Let's proceed to step 7:
If we divide 96 by 975, we get 0 and a remainder of 96.
The next digit of our result is 0. 
Result so far: 2660.0
Subtracting 0 from 96 leaves us with 96.
Append the next digit (6) from the dividend to 96 and continue with: 966 / 975

Advancing to step 8:
If we divide 966 by 975, we get 0 and a remainder of 966.
Use 0 as the next digit of our solution. 
Result so far: 26600.0
Subtracting 0 from 966 leaves us with 966.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9660, and continue the process.

Moving on to step 9:
9660 divided by 975 is 9 with a remainder of 885.
Record the quotient 9 as the next digit in the result. 
Result so far: 26600.9
If we take 8775 away from 9660, we end up with 885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8850, and continue the process.

Let's proceed to step 10:
975 goes into 8850 9 times with a remainder of 75.
The next digit of our result is 9. 
Result so far: 26600.99
The remainder is 75 after subtracting 8775 from 8850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 26600.99 with a remainder of 0.075.
