Let's divide 571648 by 8
The aim is to understand the frequency of 8 in 571648.

Moving on to step 1:
If we divide 5 by 8, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 8

Moving on to step 2:
57 divided by 8 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 56 from 57, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 8

Let's proceed to step 3:
11 divided by 8 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtract 8 from 11 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 8

Advancing to step 4:
36 divided by 8 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 714.0
Subtracting 32 from 36 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 8

Step 5:
44 divided by 8 is 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 7145.0
The remainder is 4 after subtracting 40 from 44.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 8

Step 6:
If we divide 48 by 8, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 71456.0
If we take 48 away from 48, 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 7:
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: 71456.0
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 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 71456.0
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.

The final outcome is 71456.0, with a leftover of 0.0.
