903089 ÷ 8 
The aim is to understand the frequency of 8 in 903089.

Moving on to step 1:
8 goes into 9 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 8

Advancing to step 2:
8 can be fit into 10 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 8 from 10 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 8

Advancing to step 3:
23 divided by 8 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Subtract 16 from 23 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 8

Step 4:
8 can be fit into 70 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 1128.0
Subtract 64 from 70 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 8

Let's proceed to step 5:
68 divided by 8 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 11288.0
The remainder is 4 after subtracting 64 from 68.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 8

On to step 6:
49 divided by 8 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 112886.0
If we take 48 away from 49, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
8 can be fit into 10 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 112886.1
Subtract 8 from 10 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 8 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 112886.12
Subtract 16 from 20 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.

Going ahead to step 9:
40 divided by 8 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 112886.125
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.

Going ahead to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 112886.125
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.

On to step 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 112886.125
Deduct 0 from 0 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.

The final result is 112886.125 with a remainder of 0.0.
