We look at the division of 343356 by 8 
The aim is to understand the frequency of 8 in 343356.

Moving on to step 1:
8 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 8

Advancing to step 2:
34 divided by 8 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 32 away from 34, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 8

Let's proceed to step 3:
If we divide 23 by 8, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 42.0
The remainder is 7 after subtracting 16 from 23.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 8

Let's proceed to step 4:
73 divided by 8 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 429.0
Deduct 72 from 73 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 8

Let's proceed to step 5:
When dividing 15 by 8, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 4291.0
Deduct 8 from 15 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 8

Let's proceed to step 6:
If we divide 76 by 8, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 42919.0
If we take 72 away from 76, we end up 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.

Advancing to step 7:
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: 42919.5
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.

Step 8:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 42919.5
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 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42919.5
The remainder is 0 after subtracting 0 from 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 final result is 42919.5 with a remainder of 0.0.
