We're dividing 6558869 by 935 
The aim is to understand the frequency of 935 in 6558869.

Step 1:
935 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 935

Moving on to step 2:
If we divide 65 by 935, we get 0 and a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 935

Going ahead to step 3:
If we divide 655 by 935, we get 0 and a remainder of 655.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 655 after subtracting 0 from 655.
Fetch the next digit (8) from the dividend, attach it to 655 and continue: 6558 / 935

Moving on to step 4:
When dividing 6558 by 935, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 13 after subtracting 6545 from 6558.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 935

Going ahead to step 5:
The number 935 fits into 138 0 times, leaving a remainder of 138.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we subtract 0 from 138, we get 138.
Append the next digit (6) from the dividend to 138 and continue with: 1386 / 935

Moving on to step 6:
935 goes into 1386 1 times with a remainder of 451.
The number 1 becomes the next digit in our result. 
Result so far: 701.0
Subtracting 935 from 1386 leaves us with 451.
Append the next digit (9) from the dividend to 451 and continue with: 4519 / 935

Step 7:
935 goes into 4519 4 times with a remainder of 779.
Use 4 as the next digit of our solution. 
Result so far: 7014.0
If we subtract 3740 from 4519, we get 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

On to step 8:
The number 935 fits into 7790 8 times, leaving a remainder of 310.
Use 8 as the next digit of our solution. 
Result so far: 7014.8
Deduct 7480 from 7790 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 9:
The number 935 fits into 3100 3 times, leaving a remainder of 295.
Use 3 as the next digit of our solution. 
Result so far: 7014.83
If we take 2805 away from 3100, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 10:
2950 divided by 935 is 3 with a remainder of 145.
Record the quotient 3 as the next digit in the result. 
Result so far: 7014.833
Subtract 2805 from 2950 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final outcome is 7014.833, with a leftover of 0.0145.
