Let's divide 231599 by 8
The aim is to understand the frequency of 8 in 231599.

Moving on to step 1:
2 divided by 8 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 8

Step 2:
8 goes into 23 2 times with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 16 from 23 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 8

Advancing to step 3:
8 goes into 71 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 7 after subtracting 64 from 71.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 8

Let's proceed to step 4:
If we divide 75 by 8, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 289.0
If we take 72 away from 75, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 8

On to step 5:
If we divide 39 by 8, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 2894.0
If we take 32 away from 39, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 8

Going ahead to step 6:
The number 8 fits into 79 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 28949.0
Subtracting 72 from 79 leaves us 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.

Advancing to step 7:
When dividing 70 by 8, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 28949.8
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.

Going ahead to step 8:
If we divide 60 by 8, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 28949.87
If we subtract 56 from 60, we 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.

Step 9:
40 divided by 8 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 28949.875
Deduct 40 from 40 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 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 28949.875
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.

Step 11:
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: 28949.875
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 28949.875 and a remainder of 0.0.
