We're dividing 705660 by 85 
The aim is to understand the frequency of 85 in 705660.

On to step 1:
85 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 85

On to step 2:
When dividing 70 by 85, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Append the next digit (5) from the dividend to 70 and continue with: 705 / 85

Let's proceed to step 3:
85 goes into 705 8 times with a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 680 from 705 and we're left with 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 85

Moving on to step 4:
If we divide 256 by 85, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Deduct 255 from 256 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 85

On to step 5:
When dividing 16 by 85, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 830.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 85

Advancing to step 6:
85 can be fit into 160 1 times, resulting in a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 8301.0
Subtract 85 from 160 to 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.

Moving on to step 7:
If we divide 750 by 85, we get 8 and a remainder of 70.
The next digit of our result is 8. 
Result so far: 8301.8
Subtracting 680 from 750 leaves us with 70.
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 8:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 8301.88
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.

In conclusion, the division gives 8301.88 with a balance of 0.02.
