We look at the division of 935685 by 85 
The aim is to understand the frequency of 85 in 935685.

Going ahead to step 1:
9 divided by 85 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 85

Moving on to step 2:
93 divided by 85 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 85 from 93 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 85

Going ahead to step 3:
If we divide 85 by 85, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 85 from 85 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 85

On to step 4:
The number 85 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 110.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 85

On to step 5:
The number 85 fits into 68 0 times, leaving a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 1100.0
Deduct 0 from 68 and we're left with 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 85

On to step 6:
If we divide 685 by 85, we get 8 and a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 11008.0
If we subtract 680 from 685, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
The number 85 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 11008.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
85 goes into 500 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 11008.05
Subtract 425 from 500 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.

Let's proceed to step 9:
When dividing 750 by 85, we get 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 11008.058
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 11008.0588
Deduct 680 from 700 and we're left 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.

The quotient of the division is 11008.0588, and the remainder is 0.0002.
