135039 divided by 85 
The aim is to understand the frequency of 85 in 135039.

Going ahead to step 1:
1 divided by 85 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 85

Step 2:
When dividing 13 by 85, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 85

Let's proceed to step 3:
85 goes into 135 1 times with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 85 away from 135, we end up with 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 85

Moving on to step 4:
If we divide 500 by 85, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 75 after subtracting 425 from 500.
Take the next digit (3) from the dividend and append it to 75, then repeat: 753 / 85

On to step 5:
The number 85 fits into 753 8 times, leaving a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
Subtracting 680 from 753 leaves us with 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 85

Let's proceed to step 6:
739 divided by 85 is 8 with a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 1588.0
If we take 680 away from 739, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
The number 85 fits into 590 6 times, leaving a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 1588.6
The remainder is 80 after subtracting 510 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
85 goes into 800 9 times with a remainder of 35.
The next digit of our result is 9. 
Result so far: 1588.69
Subtracting 765 from 800 leaves us 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.

On to step 9:
When dividing 350 by 85, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 1588.694
If we subtract 340 from 350, we 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.

Let's proceed to step 10:
When dividing 100 by 85, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1588.6941
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.

Step 11:
150 divided by 85 is 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1588.69411
Subtract 85 from 150 to get 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 1588.69411 with a remaining 6.5e-05.
