13150575 ÷ 8 
The aim is to understand the frequency of 8 in 13150575.

Step 1:
1 divided by 8 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 8

Moving on to step 2:
8 can be fit into 13 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 8 from 13 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 8

Let's proceed to step 3:
The number 8 fits into 51 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 3 after subtracting 48 from 51.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 8

Moving on to step 4:
8 can be fit into 35 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 164.0
The remainder is 3 after subtracting 32 from 35.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 8

Advancing to step 5:
When dividing 30 by 8, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 1643.0
Subtracting 24 from 30 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 8

Going ahead to step 6:
When dividing 65 by 8, we get 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 16438.0
Deduct 64 from 65 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 8

Step 7:
17 divided by 8 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 164382.0
The remainder is 1 after subtracting 16 from 17.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 8

Going ahead to step 8:
8 goes into 15 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1643821.0
Subtract 8 from 15 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
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: 1643821.8
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.

Advancing to step 10:
If we divide 60 by 8, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 1643821.87
Subtract 56 from 60 to 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 11:
8 can be fit into 40 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 1643821.875
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 12:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1643821.875
Subtracting 0 from 0 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 13:
If we divide 0 by 8, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1643821.875
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 result is 1643821.875 with a remainder of 0.0.
