We look at the division of 60394 by 86 
The aim is to understand the frequency of 86 in 60394.

On to step 1:
86 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 86

On to step 2:
When dividing 60 by 86, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 60 and we're left with 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 86

Let's proceed to step 3:
If we divide 603 by 86, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 602 from 603 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 86

On to step 4:
The number 86 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtracting 0 from 19 leaves us with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 86

Advancing to step 5:
86 goes into 194 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 702.0
The remainder is 22 after subtracting 172 from 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 6:
220 divided by 86 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 702.2
Subtracting 172 from 220 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
When dividing 480 by 86, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 702.25
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
When dividing 500 by 86, we get 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 702.255
If we subtract 430 from 500, we 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.

In conclusion, the division gives 702.255 with a balance of 0.007.
