We look at the division of 304219 by 85 
The aim is to understand the frequency of 85 in 304219.

Moving on to step 1:
If we divide 3 by 85, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
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

Let's proceed to step 2:
When dividing 30 by 85, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 85

Moving on to step 3:
When dividing 304 by 85, we get 3 with a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 255 from 304, we get 49.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 85

Advancing to step 4:
85 goes into 492 5 times with a remainder of 67.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 425 from 492 and we're left with 67.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 85

Going ahead to step 5:
If we divide 671 by 85, we get 7 and a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 357.0
Deduct 595 from 671 and we're left with 76.
Fetch the next digit (9) from the dividend, attach it to 76 and continue: 769 / 85

Advancing to step 6:
The number 85 fits into 769 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 3579.0
If we subtract 765 from 769, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
The number 85 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3579.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
85 can be fit into 400 4 times, resulting in a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 3579.04
If we subtract 340 from 400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
85 can be fit into 600 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 3579.047
The remainder is 5 after subtracting 595 from 600.
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 10:
If we divide 50 by 85, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 3579.047
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
85 goes into 500 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 3579.04705
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 12:
750 divided by 85 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 3579.047058
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 13:
85 goes into 700 8 times with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 3579.0470588
If we take 680 away from 700, we end up 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 quotient of the division is 3579.0470588, and the remainder is 2e-07.
