We look at the division of 641152 by 85 
The aim is to understand the frequency of 85 in 641152.

Going ahead to step 1:
The number 85 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 85

Step 2:
64 divided by 85 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 85

Let's proceed to step 3:
85 can be fit into 641 7 times, resulting in a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 595 away from 641, we end up with 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 85

On to step 4:
85 goes into 461 5 times with a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtracting 425 from 461 leaves us with 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 85

Advancing to step 5:
365 divided by 85 is 4 with a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 754.0
Deduct 340 from 365 and we're left with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 85

Step 6:
252 divided by 85 is 2 with a remainder of 82.
The next digit of our result is 2. 
Result so far: 7542.0
If we take 170 away from 252, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 7:
When dividing 820 by 85, we get 9 with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 7542.9
Subtract 765 from 820 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
85 can be fit into 550 6 times, resulting in a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 7542.96
Subtracting 510 from 550 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
400 divided by 85 is 4 with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 7542.964
Subtracting 340 from 400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
If we divide 600 by 85, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7542.9647
Deduct 595 from 600 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
The number 85 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 7542.9647
Subtract 0 from 50 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 12:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 7542.964705
If we take 425 away from 500, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
750 divided by 85 is 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 7542.9647058
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.

Advancing to step 14:
The number 85 fits into 700 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 7542.96470588
Subtracting 680 from 700 leaves us 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.

After the division, we end up with 7542.96470588 and a remainder of 2e-08.
