236311 ÷ 8 
The aim is to understand the frequency of 8 in 236311.

Going ahead to step 1:
When dividing 2 by 8, we get 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.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 8

Step 2:
23 divided by 8 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 16 from 23 and we're left with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 8

On to step 3:
If we divide 76 by 8, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 29.0
Deduct 72 from 76 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 8

On to step 4:
If we divide 43 by 8, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 295.0
If we subtract 40 from 43, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 8

Moving on to step 5:
When dividing 31 by 8, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 2953.0
The remainder is 7 after subtracting 24 from 31.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 8

Advancing to step 6:
If we divide 71 by 8, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 29538.0
The remainder is 7 after subtracting 64 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
The number 8 fits into 70 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 29538.8
Deduct 64 from 70 and we're left 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:
The number 8 fits into 60 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 29538.87
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.

Step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 29538.875
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.

Moving on to step 10:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29538.875
The remainder is 0 after subtracting 0 from 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 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: 29538.875
The remainder is 0 after subtracting 0 from 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 29538.875, with a leftover of 0.0.
