85856666 ÷ 935 
The aim is to understand the frequency of 935 in 85856666.

Step 1:
When dividing 8 by 935, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 935

Advancing to step 2:
If we divide 85 by 935, we get 0 and a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Append the next digit (8) from the dividend to 85 and continue with: 858 / 935

Step 3:
935 can be fit into 858 0 times, resulting in a remainder of 858.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 858, we end up with 858.
Take the next digit (5) from the dividend and append it to 858, then repeat: 8585 / 935

Going ahead to step 4:
935 goes into 8585 9 times with a remainder of 170.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 8415 from 8585 leaves us with 170.
Take the next digit (6) from the dividend and append it to 170, then repeat: 1706 / 935

Let's proceed to step 5:
The number 935 fits into 1706 1 times, leaving a remainder of 771.
The next digit of our result is 1. 
Result so far: 91.0
Subtracting 935 from 1706 leaves us with 771.
Include the next digit (6) from the dividend after 771, then repeat: 7716 / 935

Step 6:
935 goes into 7716 8 times with a remainder of 236.
The next digit of our result is 8. 
Result so far: 918.0
Subtracting 7480 from 7716 leaves us with 236.
Fetch the next digit (6) from the dividend, attach it to 236 and continue: 2366 / 935

Let's proceed to step 7:
935 can be fit into 2366 2 times, resulting in a remainder of 496.
The next digit of our result is 2. 
Result so far: 9182.0
If we subtract 1870 from 2366, we get 496.
Take the next digit (6) from the dividend and append it to 496, then repeat: 4966 / 935

Moving on to step 8:
935 goes into 4966 5 times with a remainder of 291.
Write down 5 as next digit of the result. 
Result so far: 91825.0
Subtracting 4675 from 4966 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 9:
The number 935 fits into 2910 3 times, leaving a remainder of 105.
The next digit of our result is 3. 
Result so far: 91825.3
If we take 2805 away from 2910, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 10:
1050 divided by 935 is 1 with a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 91825.31
Subtracting 935 from 1050 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 11:
If we divide 1150 by 935, we get 1 and a remainder of 215.
Record the quotient 1 as the next digit in the result. 
Result so far: 91825.311
Subtract 935 from 1150 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

The final result is 91825.311 with a remainder of 0.0215.
