221575 ÷ 8 
The aim is to understand the frequency of 8 in 221575.

Advancing to step 1:
If we divide 2 by 8, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 8

Going ahead to step 2:
If we divide 22 by 8, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 16 from 22 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 8

Let's proceed to step 3:
The number 8 fits into 61 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 27.0
If we take 56 away from 61, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 8

Going ahead to step 4:
When dividing 55 by 8, we get 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 276.0
Subtract 48 from 55 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 8

Step 5:
When dividing 77 by 8, we get 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 2769.0
Subtract 72 from 77 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 8

Advancing to step 6:
8 goes into 55 6 times with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 27696.0
Deduct 48 from 55 and we're left 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:
8 goes into 70 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 27696.8
If we take 64 away from 70, we end up 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: 27696.87
Subtracting 56 from 60 leaves us 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.

Moving on to step 9:
8 goes into 40 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 27696.875
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.

Advancing to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 27696.875
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.

Let's proceed to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27696.875
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 27696.875, with a leftover of 0.0.
