We're dividing 264504 by 85 
The aim is to understand the frequency of 85 in 264504.

Going ahead to step 1:
85 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 85

Step 2:
When dividing 26 by 85, we get 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 85

Moving on to step 3:
264 divided by 85 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 255 from 264 and we're left with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 85

Advancing to step 4:
If we divide 95 by 85, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 85 from 95 leaves us with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 85

Advancing to step 5:
When dividing 100 by 85, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 311.0
Subtracting 85 from 100 leaves us with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 85

On to step 6:
85 can be fit into 154 1 times, resulting in a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 3111.0
If we take 85 away from 154, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
85 can be fit into 690 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 3111.8
Subtract 680 from 690 to 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.

Let's proceed to step 8:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 3111.81
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
85 goes into 150 1 times with a remainder of 65.
The next digit of our result is 1. 
Result so far: 3111.811
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 3111.811, with a leftover of 0.0065.
