582415 ÷ 8 
The aim is to understand the frequency of 8 in 582415.

Let's proceed to step 1:
If we divide 5 by 8, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 8

Step 2:
8 can be fit into 58 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 56 from 58 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 8

Moving on to step 3:
8 goes into 22 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtract 16 from 22 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 8

Going ahead to step 4:
The number 8 fits into 64 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 728.0
If we take 64 away from 64, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 8

Let's proceed to step 5:
When dividing 1 by 8, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 7280.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 8

Let's proceed to step 6:
8 can be fit into 15 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 72801.0
If we take 8 away from 15, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 8, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 72801.8
Subtracting 64 from 70 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
60 divided by 8 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 72801.87
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
8 goes into 40 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 72801.875
If we take 40 away from 40, 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 10:
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: 72801.875
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.

Step 11:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 72801.875
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.

The final outcome is 72801.875, with a leftover of 0.0.
