We look at the division of 429336 by 85 
The aim is to understand the frequency of 85 in 429336.

Step 1:
If we divide 4 by 85, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 85

Step 2:
If we divide 42 by 85, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 85

Advancing to step 3:
The number 85 fits into 429 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 4 after subtracting 425 from 429.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 85

Let's proceed to step 4:
If we divide 43 by 85, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 85

Moving on to step 5:
When dividing 433 by 85, we get 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 505.0
If we take 425 away from 433, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 85

Going ahead to step 6:
The number 85 fits into 86 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 5051.0
Deduct 85 from 86 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
If we divide 10 by 85, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 5051.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 85, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 5051.01
If we subtract 85 from 100, we 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.

Step 9:
If we divide 150 by 85, we get 1 and a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 5051.011
Deduct 85 from 150 and we're left 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 5051.011 with a remaining 0.0065.
