We're dividing 869723 by 8 
The aim is to understand the frequency of 8 in 869723.

Going ahead to step 1:
When dividing 8 by 8, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 8 away from 8, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 8

Step 2:
8 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 8

Let's proceed to step 3:
8 can be fit into 69 8 times, resulting in a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Deduct 64 from 69 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 8

Advancing to step 4:
When dividing 57 by 8, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 1087.0
The remainder is 1 after subtracting 56 from 57.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 8

Let's proceed to step 5:
The number 8 fits into 12 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 10871.0
Subtract 8 from 12 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 8

On to step 6:
43 divided by 8 is 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 108715.0
Subtract 40 from 43 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 8, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 108715.3
Subtracting 24 from 30 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:
60 divided by 8 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 108715.37
Deduct 56 from 60 and we're left 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.

On to step 9:
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: 108715.375
Subtract 40 from 40 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.

On 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: 108715.375
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.

Let's proceed to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 108715.375
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 quotient of the division is 108715.375, and the remainder is 0.0.
