531551 divided by 8 
The aim is to understand the frequency of 8 in 531551.

Moving on to step 1:
8 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 8

Step 2:
53 divided by 8 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 48 from 53 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 8

Going ahead to step 3:
8 goes into 51 6 times with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 66.0
The remainder is 3 after subtracting 48 from 51.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 8

On to step 4:
8 can be fit into 35 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 664.0
Subtracting 32 from 35 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 8

Step 5:
35 divided by 8 is 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 6644.0
The remainder is 3 after subtracting 32 from 35.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 8

Let's proceed to step 6:
If we divide 31 by 8, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 66443.0
Subtract 24 from 31 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 8 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 66443.8
If we subtract 64 from 70, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 66443.87
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 8 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 66443.875
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:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 66443.875
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.

Moving on to step 11:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 66443.875
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.

After the division, we end up with 66443.875 and a remainder of 0.0.
