We're dividing 91253 by 8 
The aim is to understand the frequency of 8 in 91253.

Let's proceed to step 1:
9 divided by 8 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 8 from 9 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 8

On to step 2:
When dividing 11 by 8, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 8 away from 11, we end up with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 8

Going ahead to step 3:
When dividing 32 by 8, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 114.0
If we subtract 32 from 32, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 8

Going ahead to step 4:
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: 1140.0
Subtract 0 from 5 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 8

Moving on to step 5:
53 divided by 8 is 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 11406.0
Subtract 48 from 53 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 6:
When dividing 50 by 8, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 11406.6
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
8 goes into 20 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 11406.62
Subtracting 16 from 20 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.

Let's proceed to step 8:
When dividing 40 by 8, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11406.625
Subtracting 40 from 40 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.

Step 9:
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: 11406.625
If we subtract 0 from 0, 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.

On to step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11406.625
If we subtract 0 from 0, 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.

After the division, we end up with 11406.625 and a remainder of 0.0.
