We're dividing 35132015 by 85 
The aim is to understand the frequency of 85 in 35132015.

On to step 1:
The number 85 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 85

Let's proceed to step 2:
35 divided by 85 is 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Append the next digit (1) from the dividend to 35 and continue with: 351 / 85

On to step 3:
When dividing 351 by 85, we get 4 with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 340 from 351 leaves us with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 85

Let's proceed to step 4:
The number 85 fits into 113 1 times, leaving a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we subtract 85 from 113, we get 28.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 85

Going ahead to step 5:
If we divide 282 by 85, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 413.0
The remainder is 27 after subtracting 255 from 282.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 85

Step 6:
The number 85 fits into 270 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 4133.0
If we take 255 away from 270, we end up with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 85

Advancing to step 7:
85 can be fit into 151 1 times, resulting in a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 41331.0
Subtracting 85 from 151 leaves us with 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 85

Going ahead to step 8:
If we divide 665 by 85, we get 7 and a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 413317.0
The remainder is 70 after subtracting 595 from 665.
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 9:
The number 85 fits into 700 8 times, leaving a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 413317.8
Subtracting 680 from 700 leaves us 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.

Let's proceed to step 10:
200 divided by 85 is 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 413317.82
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.

Advancing to step 11:
85 can be fit into 300 3 times, resulting in a remainder of 45.
The next digit of our result is 3. 
Result so far: 413317.823
Deduct 255 from 300 and we're left 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.

Let's proceed to step 12:
If we divide 450 by 85, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 413317.8235
Deduct 425 from 450 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 13:
If we divide 250 by 85, we get 2 and a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 413317.82352
Deduct 170 from 250 and we're left with 80.
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 14:
85 goes into 800 9 times with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 413317.823529
Subtract 765 from 800 to 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.

On to step 15:
350 divided by 85 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 413317.8235294
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.

On to step 16:
85 goes into 100 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 413317.82352941
Deduct 85 from 100 and we're left 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.

The final result is 413317.82352941 with a remainder of 1.5e-08.
