We look at the division of 912603 by 8 
The aim is to understand the frequency of 8 in 912603.

Going ahead to step 1:
When dividing 9 by 8, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 8 from 9 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 8

Step 2:
If we divide 11 by 8, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 8 from 11 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 8

On to step 3:
The number 8 fits into 32 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtract 32 from 32 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 8

Moving on to step 4:
The number 8 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 1140.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 8

Moving on to step 5:
8 can be fit into 60 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 11407.0
Subtract 56 from 60 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 8

Advancing to step 6:
8 can be fit into 43 5 times, resulting in a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 114075.0
The remainder is 3 after subtracting 40 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 8, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 114075.3
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.

Advancing to step 8:
If we divide 60 by 8, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 114075.37
Subtracting 56 from 60 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.

On to step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 114075.375
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:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 114075.375
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.

Going ahead to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 114075.375
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.

Our division results in 114075.375 with a remaining 0.0.
