We look at the division of 675609 by 85 
The aim is to understand the frequency of 85 in 675609.

Let's proceed to step 1:
85 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 85

Let's proceed to step 2:
85 can be fit into 67 0 times, resulting in a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Bring next digit (5) of the dividend behind the 67 and repeat the process: 675 / 85

Step 3:
The number 85 fits into 675 7 times, leaving a remainder of 80.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 595 from 675 and we're left with 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 85

Going ahead to step 4:
806 divided by 85 is 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 79.0
Subtracting 765 from 806 leaves us with 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 85

Let's proceed to step 5:
The number 85 fits into 410 4 times, leaving a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 794.0
If we subtract 340 from 410, we get 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 85

Advancing to step 6:
If we divide 709 by 85, we get 8 and a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 7948.0
Subtract 680 from 709 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
When dividing 290 by 85, we get 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 7948.3
Subtracting 255 from 290 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
The number 85 fits into 350 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 7948.34
Subtract 340 from 350 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 7948.341
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
150 divided by 85 is 1 with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 7948.3411
Subtracting 85 from 150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 7948.3411 with a remaining 0.00065.
