122512 divided by 8 
The aim is to understand the frequency of 8 in 122512.

Step 1:
8 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 8

On to step 2:
8 goes into 12 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 8 from 12, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 8

Advancing to step 3:
8 can be fit into 42 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 40 from 42, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 8

Step 4:
If we divide 25 by 8, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Deduct 24 from 25 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 8

Going ahead to step 5:
11 divided by 8 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1531.0
Subtracting 8 from 11 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 8

Let's proceed to step 6:
8 can be fit into 32 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 15314.0
If we take 32 away from 32, 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.

Going ahead to step 7:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15314.0
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.

Moving on to step 8:
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: 15314.0
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 final result is 15314.0 with a remainder of 0.0.
