We look at the division of 543033 by 86 
The aim is to understand the frequency of 86 in 543033.

Let's proceed to step 1:
86 goes into 5 0 times 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.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 86

Let's proceed to step 2:
When dividing 54 by 86, we get 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 86

Going ahead to step 3:
If we divide 543 by 86, we get 6 and a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 516 away from 543, we end up with 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 86

On to step 4:
If we divide 270 by 86, we get 3 and a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we take 258 away from 270, we end up with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 86

Let's proceed to step 5:
123 divided by 86 is 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 631.0
Subtract 86 from 123 to get 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 86

Going ahead to step 6:
When dividing 373 by 86, we get 4 with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 6314.0
If we subtract 344 from 373, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
The number 86 fits into 290 3 times, leaving a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 6314.3
If we take 258 away from 290, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
When dividing 320 by 86, we get 3 with a remainder of 62.
The next digit of our result is 3. 
Result so far: 6314.33
If we take 258 away from 320, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 6314.33 and a remainder of 0.062.
