We're dividing 557819 by 85 
The aim is to understand the frequency of 85 in 557819.

Step 1:
5 divided by 85 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 85

Going ahead to step 2:
The number 85 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 85

Advancing to step 3:
557 divided by 85 is 6 with a remainder of 47.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 510 from 557 to get 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 85

Going ahead to step 4:
If we divide 478 by 85, we get 5 and a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
The remainder is 53 after subtracting 425 from 478.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 85

Advancing to step 5:
When dividing 531 by 85, we get 6 with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 656.0
Subtracting 510 from 531 leaves us with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 85

Moving on to step 6:
85 goes into 219 2 times with a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 6562.0
The remainder is 49 after subtracting 170 from 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
85 can be fit into 490 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 6562.5
Deduct 425 from 490 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 8:
When dividing 650 by 85, we get 7 with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 6562.57
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.

Let's proceed to step 9:
If we divide 550 by 85, we get 6 and a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 6562.576
The remainder is 40 after subtracting 510 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
85 can be fit into 400 4 times, resulting in a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 6562.5764
Subtract 340 from 400 to 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 11:
The number 85 fits into 600 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 6562.57647
If we subtract 595 from 600, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
85 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 6562.57647
Subtracting 0 from 50 leaves us 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.

On to step 13:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 6562.5764705
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 14:
750 divided by 85 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 6562.57647058
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.

Our division results in 6562.57647058 with a remaining 7e-08.
