We look at the division of 35580614 by 85 
The aim is to understand the frequency of 85 in 35580614.

Step 1:
85 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 85

Moving on to step 2:
The number 85 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 85

On to step 3:
The number 85 fits into 355 4 times, leaving a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 340 from 355, we get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 85

On to step 4:
85 goes into 158 1 times with a remainder of 73.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 85 from 158 leaves us with 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 85

Let's proceed to step 5:
When dividing 730 by 85, we get 8 with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 418.0
If we take 680 away from 730, we end up with 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 85

Moving on to step 6:
85 goes into 506 5 times with a remainder of 81.
Record the quotient 5 as the next digit in the result. 
Result so far: 4185.0
Deduct 425 from 506 and we're left with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 85

Going ahead to step 7:
85 can be fit into 811 9 times, resulting in a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 41859.0
Subtract 765 from 811 to get 46.
Grab the next digit (4) from the dividend, add it to 46, then carry on: 464 / 85

Advancing to step 8:
464 divided by 85 is 5 with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 418595.0
Subtracting 425 from 464 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 9:
The number 85 fits into 390 4 times, leaving a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 418595.4
Deduct 340 from 390 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
500 divided by 85 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 418595.45
If we take 425 away from 500, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
85 goes into 750 8 times with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 418595.458
Subtracting 680 from 750 leaves us 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 12:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 418595.4588
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.

The final outcome is 418595.4588, with a leftover of 0.0002.
