We look at the division of 93987 by 85 
The aim is to understand the frequency of 85 in 93987.

Advancing to step 1:
The number 85 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 85

Step 2:
93 divided by 85 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 85 from 93 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 85

On to step 3:
The number 85 fits into 89 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 85 from 89 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 85

Moving on to step 4:
85 goes into 48 0 times with a remainder of 48.
The next digit of our result is 0. 
Result so far: 110.0
Subtract 0 from 48 to get 48.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 85

Step 5:
When dividing 487 by 85, we get 5 with a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 1105.0
The remainder is 62 after subtracting 425 from 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 6:
The number 85 fits into 620 7 times, leaving a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 1105.7
If we subtract 595 from 620, we 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.

Moving on to step 7:
85 can be fit into 250 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 1105.72
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
85 can be fit into 800 9 times, resulting in a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 1105.729
Deduct 765 from 800 and we're left 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.

Going ahead to step 9:
350 divided by 85 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 1105.7294
The remainder is 10 after subtracting 340 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
The number 85 fits into 100 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 1105.72941
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
85 can be fit into 150 1 times, resulting in a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1105.729411
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.

In conclusion, the division gives 1105.729411 with a balance of 6.5e-06.
