We're dividing 903774 by 8 
The aim is to understand the frequency of 8 in 903774.

Advancing to step 1:
9 divided by 8 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 8 away from 9, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 8

On to step 2:
8 can be fit into 10 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 8 from 10 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 8

On to step 3:
When dividing 23 by 8, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we subtract 16 from 23, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 8

Advancing to step 4:
When dividing 77 by 8, we get 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 1129.0
Subtract 72 from 77 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 8

Going ahead to step 5:
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: 11297.0
Deduct 56 from 57 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 8

Moving on to step 6:
When dividing 14 by 8, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 112971.0
Deduct 8 from 14 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 7:
When dividing 60 by 8, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 112971.7
If we subtract 56 from 60, we 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 8:
40 divided by 8 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 112971.75
If we take 40 away from 40, 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.

Let's proceed to step 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 112971.75
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.

Let's proceed to step 10:
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: 112971.75
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.

The final outcome is 112971.75, with a leftover of 0.0.
