Let's divide 781081 by 8
The aim is to understand the frequency of 8 in 781081.

Let's proceed to step 1:
7 divided by 8 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 8

Advancing to step 2:
8 can be fit into 78 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 72 from 78 leaves us with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 8

Going ahead to step 3:
When dividing 61 by 8, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 97.0
The remainder is 5 after subtracting 56 from 61.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 8

Step 4:
When dividing 50 by 8, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 976.0
If we subtract 48 from 50, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 8

Going ahead to step 5:
The number 8 fits into 28 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 9763.0
Deduct 24 from 28 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 8

Going ahead to step 6:
8 goes into 41 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 97635.0
The remainder is 1 after subtracting 40 from 41.
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:
When dividing 10 by 8, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 97635.1
If we subtract 8 from 10, we 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.

Moving on to step 8:
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: 97635.12
Deduct 16 from 20 and we're left 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.
The number 5 becomes the next digit in our result. 
Result so far: 97635.125
Subtracting 40 from 40 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.
The next digit of our result is 0. 
Result so far: 97635.125
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.

Moving on to step 11:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 97635.125
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.

The final result is 97635.125 with a remainder of 0.0.
