103408 ÷ 8 
The aim is to understand the frequency of 8 in 103408.

Step 1:
When dividing 1 by 8, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 8

Advancing to step 2:
If we divide 10 by 8, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 8 from 10 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 8

Advancing to step 3:
8 can be fit into 23 2 times, resulting in a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 7 after subtracting 16 from 23.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 8

On to step 4:
When dividing 74 by 8, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtracting 72 from 74 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 8

Moving on to step 5:
If we divide 20 by 8, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1292.0
If we take 16 away from 20, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 8

Going ahead to step 6:
48 divided by 8 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 12926.0
If we subtract 48 from 48, we 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.

Step 7:
When dividing 0 by 8, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12926.0
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.

Let's proceed to step 8:
8 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12926.0
If we subtract 0 from 0, we 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.

The quotient of the division is 12926.0, and the remainder is 0.0.
