We look at the division of 304230 by 85 
The aim is to understand the frequency of 85 in 304230.

Let's proceed to step 1:
85 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 85

Moving on to step 2:
The number 85 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 85

Going ahead to step 3:
When dividing 304 by 85, we get 3 with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 255 from 304 and we're left with 49.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 85

Moving on to step 4:
85 can be fit into 492 5 times, resulting in a remainder of 67.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 425 away from 492, we end up with 67.
Include the next digit (3) from the dividend after 67, then repeat: 673 / 85

Going ahead to step 5:
673 divided by 85 is 7 with a remainder of 78.
The next digit of our result is 7. 
Result so far: 357.0
If we subtract 595 from 673, we get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 85

Step 6:
780 divided by 85 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 3579.0
Deduct 765 from 780 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.

Let's proceed to step 7:
When dividing 150 by 85, we get 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 3579.1
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.

Going ahead to step 8:
85 goes into 650 7 times with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 3579.17
Subtract 595 from 650 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 9:
The number 85 fits into 550 6 times, leaving a remainder of 40.
The next digit of our result is 6. 
Result so far: 3579.176
Subtract 510 from 550 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
When dividing 400 by 85, we get 4 with a remainder of 60.
The next digit of our result is 4. 
Result so far: 3579.1764
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
600 divided by 85 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 3579.17647
Subtracting 595 from 600 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
The number 85 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 3579.17647
If we take 0 away from 50, we end up 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 13:
500 divided by 85 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 3579.1764705
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
750 divided by 85 is 8 with a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 3579.17647058
Deduct 680 from 750 and we're left 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.

The final outcome is 3579.17647058, with a leftover of 7e-08.
