We're dividing 394414 by 8 
The aim is to understand the frequency of 8 in 394414.

On to step 1:
3 divided by 8 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 8

Step 2:
The number 8 fits into 39 4 times, leaving a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 7 after subtracting 32 from 39.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 8

Moving on to step 3:
8 goes into 74 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtracting 72 from 74 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 8

Advancing to step 4:
24 divided by 8 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 493.0
If we subtract 24 from 24, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 8

Advancing to step 5:
1 divided by 8 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 4930.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 8

Advancing to step 6:
The number 8 fits into 14 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 49301.0
Subtract 8 from 14 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 8 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 49301.7
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 49301.75
If we take 40 away from 40, 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.

Advancing to step 9:
8 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49301.75
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.

On to step 10:
0 divided by 8 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 49301.75
Subtracting 0 from 0 leaves us 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.

Our division results in 49301.75 with a remaining 0.0.
