We're dividing 413881 by 8 
The aim is to understand the frequency of 8 in 413881.

Advancing to step 1:
8 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 8

Let's proceed to step 2:
When dividing 41 by 8, we get 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 40 from 41 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 8

Moving on to step 3:
The number 8 fits into 13 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we subtract 8 from 13, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 8

Going ahead to step 4:
The number 8 fits into 58 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 517.0
Subtracting 56 from 58 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 8

Let's proceed to step 5:
28 divided by 8 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 5173.0
Subtract 24 from 28 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 8

Let's proceed 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: 51735.0
Subtract 40 from 41 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to 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: 51735.1
Subtract 8 from 10 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:
When dividing 20 by 8, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 51735.12
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.

On to step 9:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 51735.125
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.

On 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: 51735.125
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.

Advancing to step 11:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 51735.125
If we subtract 0 from 0, 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.

After the division, we end up with 51735.125 and a remainder of 0.0.
