Let's divide 394686 by 8
The aim is to understand the frequency of 8 in 394686.

Step 1:
8 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 8

Advancing to step 2:
8 can be fit into 39 4 times, resulting in a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 32 from 39, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 8

Advancing to step 3:
When dividing 74 by 8, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
The remainder is 2 after subtracting 72 from 74.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 8

Advancing to step 4:
If we divide 26 by 8, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 493.0
If we take 24 away from 26, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 8

Going ahead to step 5:
If we divide 28 by 8, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 4933.0
Subtract 24 from 28 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 8

Step 6:
46 divided by 8 is 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 49335.0
Subtracting 40 from 46 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 8 fits into 60 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 49335.7
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
40 divided by 8 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 49335.75
Subtract 40 from 40 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 49335.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49335.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 49335.75 with a balance of 0.0.
