We look at the division of 530628 by 8 
The aim is to understand the frequency of 8 in 530628.

Moving on to step 1:
5 divided by 8 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 8

Moving on to step 2:
The number 8 fits into 53 6 times, leaving a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 48 from 53 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 8

Advancing to step 3:
8 goes into 50 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we take 48 away from 50, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 8

Moving on to step 4:
8 can be fit into 26 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 663.0
Subtract 24 from 26 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 8

Advancing to step 5:
8 goes into 22 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 6632.0
Subtracting 16 from 22 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 8

Going ahead to step 6:
When dividing 68 by 8, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 66328.0
If we take 64 away from 68, 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.

Step 7:
When dividing 40 by 8, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 66328.5
If we subtract 40 from 40, 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.

Let's proceed to step 8:
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: 66328.5
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.

Going ahead to step 9:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 66328.5
Subtract 0 from 0 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.

The final result is 66328.5 with a remainder of 0.0.
