We divide 563823 by 85
The aim is to understand the frequency of 85 in 563823.

Step 1:
When dividing 5 by 85, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 85

Moving on to step 2:
When dividing 56 by 85, we get 0 with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Grab the next digit (3) from the dividend, add it to 56, then carry on: 563 / 85

Step 3:
85 goes into 563 6 times with a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 53 after subtracting 510 from 563.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 85

Let's proceed to step 4:
The number 85 fits into 538 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we take 510 away from 538, we end up with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 85

Going ahead to step 5:
282 divided by 85 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 663.0
If we subtract 255 from 282, we get 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 85

Step 6:
If we divide 273 by 85, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 6633.0
If we subtract 255 from 273, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
85 goes into 180 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 6633.2
Subtract 170 from 180 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.

Advancing to step 8:
85 goes into 100 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 6633.21
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.

Advancing to step 9:
85 can be fit into 150 1 times, resulting in a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 6633.211
Subtracting 85 from 150 leaves us 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.

After the division, we end up with 6633.211 and a remainder of 0.0065.
