803621 divided by 8 
The aim is to understand the frequency of 8 in 803621.

On to step 1:
If we divide 8 by 8, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 8 from 8 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 8

Step 2:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 8

Going ahead to step 3:
8 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 8

Going ahead to step 4:
8 goes into 36 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 1004.0
If we subtract 32 from 36, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 8

Advancing to step 5:
The number 8 fits into 42 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 10045.0
Subtract 40 from 42 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 8

On to step 6:
If we divide 21 by 8, we get 2 and a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 100452.0
The remainder is 5 after subtracting 16 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 8, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 100452.6
Subtract 48 from 50 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.
Write down 2 as next digit of the result. 
Result so far: 100452.62
Subtracting 16 from 20 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.

Moving on to step 9:
40 divided by 8 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 100452.625
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:
0 divided by 8 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 100452.625
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.
The next digit of our result is 0. 
Result so far: 100452.625
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.

In conclusion, the division gives 100452.625 with a balance of 0.0.
