We're dividing 519291 by 8 
The aim is to understand the frequency of 8 in 519291.

Advancing to step 1:
5 divided by 8 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 8

Advancing to step 2:
8 goes into 51 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 48 from 51, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 8

On to step 3:
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: 64.0
Deduct 32 from 39 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 8

Step 4:
72 divided by 8 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 649.0
Deduct 72 from 72 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 8

Advancing to step 5:
If we divide 9 by 8, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 6491.0
If we subtract 8 from 9, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 8

Advancing to step 6:
If we divide 11 by 8, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 64911.0
If we subtract 8 from 11, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 8, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 64911.3
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
The number 8 fits into 60 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 64911.37
If we subtract 56 from 60, we 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.

On to step 9:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 64911.375
Deduct 40 from 40 and we're left 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 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 64911.375
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.

Let's proceed 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: 64911.375
Deduct 0 from 0 and we're left 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 64911.375 with a remainder of 0.0.
