We're dividing 406519 by 8 
The aim is to understand the frequency of 8 in 406519.

Advancing to step 1:
The number 8 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 8

Let's proceed to step 2:
8 goes into 40 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 40 from 40 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 8

On to step 3:
If we divide 6 by 8, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 8

Step 4:
65 divided by 8 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 508.0
If we subtract 64 from 65, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 8

Going ahead to step 5:
8 goes into 11 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 5081.0
Subtracting 8 from 11 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 8

Going ahead to step 6:
8 can be fit into 39 4 times, resulting in a remainder of 7.
The next digit of our result is 4. 
Result so far: 50814.0
Subtracting 32 from 39 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.

On to step 7:
8 can be fit into 70 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 50814.8
The remainder is 6 after subtracting 64 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 8, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 50814.87
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.

Step 9:
8 goes into 40 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 50814.875
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.

Advancing 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: 50814.875
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.

On to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50814.875
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.

After the division, we end up with 50814.875 and a remainder of 0.0.
