We look at the division of 333887 by 85 
The aim is to understand the frequency of 85 in 333887.

Going ahead to step 1:
The number 85 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 85

Moving on to step 2:
33 divided by 85 is 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 85

Moving on to step 3:
When dividing 333 by 85, we get 3 with a remainder of 78.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 255 from 333 to get 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 85

Let's proceed to step 4:
85 goes into 788 9 times with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 765 from 788 to get 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 85

Step 5:
If we divide 238 by 85, we get 2 and a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 392.0
If we take 170 away from 238, we end up with 68.
Include the next digit (7) from the dividend after 68, then repeat: 687 / 85

Advancing to step 6:
687 divided by 85 is 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 3928.0
Subtracting 680 from 687 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 85, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 3928.0
If we take 0 away from 70, we end up 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.

Going ahead to step 8:
700 divided by 85 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 3928.08
Subtract 680 from 700 to 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.

Moving on to step 9:
The number 85 fits into 200 2 times, leaving a remainder of 30.
The next digit of our result is 2. 
Result so far: 3928.082
Subtract 170 from 200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 85, we get 3 with a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 3928.0823
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
The number 85 fits into 450 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 3928.08235
Subtract 425 from 450 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
The number 85 fits into 250 2 times, leaving a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 3928.082352
The remainder is 80 after subtracting 170 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
If we divide 800 by 85, we get 9 and a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 3928.0823529
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
85 can be fit into 350 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 3928.08235294
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.

The final outcome is 3928.08235294, with a leftover of 1e-08.
