900983 ÷ 8 
The aim is to understand the frequency of 8 in 900983.

Moving on to step 1:
The number 8 fits into 9 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 8 from 9, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 8

Step 2:
The number 8 fits into 10 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 8 from 10 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 8

Going ahead to step 3:
When dividing 20 by 8, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtracting 16 from 20 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 8

Moving on to step 4:
When dividing 49 by 8, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1126.0
Deduct 48 from 49 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 8

Step 5:
If we divide 18 by 8, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 11262.0
If we take 16 away from 18, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 8

Let's proceed to step 6:
8 can be fit into 23 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 112622.0
Subtracting 16 from 23 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
70 divided by 8 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 112622.8
If we take 64 away from 70, we end up 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: 112622.87
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.

Moving on to step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 112622.875
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.

Advancing to step 10:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 112622.875
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.

Going ahead to step 11:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 112622.875
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.

The final result is 112622.875 with a remainder of 0.0.
