Let's divide 509577 by 85
The aim is to understand the frequency of 85 in 509577.

Let's proceed to step 1:
5 divided by 85 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 85

Advancing to step 2:
50 divided by 85 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Bring next digit (9) of the dividend behind the 50 and repeat the process: 509 / 85

Let's proceed to step 3:
If we divide 509 by 85, we get 5 and a remainder of 84.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 425 away from 509, we end up with 84.
Fetch the next digit (5) from the dividend, attach it to 84 and continue: 845 / 85

Moving on to step 4:
85 can be fit into 845 9 times, resulting in a remainder of 80.
The next digit of our result is 9. 
Result so far: 59.0
Subtracting 765 from 845 leaves us with 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 85

Moving on to step 5:
807 divided by 85 is 9 with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 599.0
The remainder is 42 after subtracting 765 from 807.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 85

Advancing to step 6:
The number 85 fits into 427 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5995.0
Deduct 425 from 427 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 85 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5995.0
If we subtract 0 from 20, 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.

Going ahead to step 8:
200 divided by 85 is 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 5995.02
The remainder is 30 after subtracting 170 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
When dividing 300 by 85, we get 3 with a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 5995.023
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
When dividing 450 by 85, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 5995.0235
If we subtract 425 from 450, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
When dividing 250 by 85, we get 2 with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 5995.02352
Subtract 170 from 250 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
If we divide 800 by 85, we get 9 and a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 5995.023529
Subtracting 765 from 800 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
When dividing 350 by 85, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 5995.0235294
If we subtract 340 from 350, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
85 goes into 100 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 5995.02352941
Subtracting 85 from 100 leaves us 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.

The final result is 5995.02352941 with a remainder of 1.5e-08.
