583458 ÷ 8 
The aim is to understand the frequency of 8 in 583458.

Advancing to step 1:
If we divide 5 by 8, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 8

Going ahead to step 2:
If we divide 58 by 8, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 56 from 58 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 8

Step 3:
When dividing 23 by 8, we get 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
If we take 16 away from 23, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 8

Let's proceed to step 4:
8 goes into 74 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 729.0
If we subtract 72 from 74, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 8

Step 5:
8 can be fit into 25 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 7293.0
Subtracting 24 from 25 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 8

Let's proceed to step 6:
8 can be fit into 18 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 72932.0
Subtract 16 from 18 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
8 goes into 20 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 72932.2
The remainder is 4 after subtracting 16 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
40 divided by 8 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 72932.25
Subtracting 40 from 40 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.

Advancing to step 9:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 72932.25
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.

Moving on to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 72932.25
Deduct 0 from 0 and we're left 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 72932.25, with a leftover of 0.0.
