We're dividing 579485 by 85 
The aim is to understand the frequency of 85 in 579485.

Step 1:
If we divide 5 by 85, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 85

Let's proceed to step 2:
85 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 85

Moving on to step 3:
When dividing 579 by 85, we get 6 with a remainder of 69.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 69 after subtracting 510 from 579.
Append the next digit (4) from the dividend to 69 and continue with: 694 / 85

On to step 4:
694 divided by 85 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 68.0
The remainder is 14 after subtracting 680 from 694.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 85

Advancing to step 5:
When dividing 148 by 85, we get 1 with a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 681.0
Subtract 85 from 148 to get 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 85

Step 6:
When dividing 635 by 85, we get 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 6817.0
Subtracting 595 from 635 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.

Going ahead to step 7:
If we divide 400 by 85, we get 4 and a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 6817.4
Subtracting 340 from 400 leaves us 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.

Let's proceed to step 8:
85 goes into 600 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 6817.47
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.

Let's proceed to step 9:
50 divided by 85 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 6817.47
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
When dividing 500 by 85, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 6817.4705
If we subtract 425 from 500, we 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.

Step 11:
When dividing 750 by 85, we get 8 with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 6817.47058
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
When dividing 700 by 85, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 6817.470588
If we subtract 680 from 700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 6817.470588 and a remainder of 2e-06.
