We're dividing 658976 by 85 
The aim is to understand the frequency of 85 in 658976.

Step 1:
If we divide 6 by 85, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 85

Step 2:
The number 85 fits into 65 0 times, leaving a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 85

Step 3:
85 can be fit into 658 7 times, resulting in a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 595 from 658, we get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 85

Advancing to step 4:
85 goes into 639 7 times with a remainder of 44.
The next digit of our result is 7. 
Result so far: 77.0
If we subtract 595 from 639, we get 44.
Include the next digit (7) from the dividend after 44, then repeat: 447 / 85

Advancing to step 5:
85 can be fit into 447 5 times, resulting in a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 775.0
If we take 425 away from 447, we end up with 22.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 85

Advancing to step 6:
When dividing 226 by 85, we get 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 7752.0
Subtracting 170 from 226 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
560 divided by 85 is 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 7752.6
Subtract 510 from 560 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
85 can be fit into 500 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 7752.65
If we subtract 425 from 500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 9:
85 goes into 750 8 times with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 7752.658
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
85 can be fit into 700 8 times, resulting in a remainder of 20.
The next digit of our result is 8. 
Result so far: 7752.6588
If we subtract 680 from 700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 7752.6588 with a remaining 0.0002.
