515046 ÷ 8 
The aim is to understand the frequency of 8 in 515046.

Going ahead to step 1:
8 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 8

Going ahead to step 2:
If we divide 51 by 8, we get 6 and a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 3 after subtracting 48 from 51.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 8

Moving on to step 3:
8 goes into 35 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 32 from 35 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 8

Advancing to step 4:
8 can be fit into 30 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 643.0
Deduct 24 from 30 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 8

Moving on to step 5:
64 divided by 8 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 6438.0
Subtracting 64 from 64 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 8

Let's proceed to step 6:
If we divide 6 by 8, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 64380.0
Subtracting 0 from 6 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 8 fits into 60 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 64380.7
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.

Let's proceed to step 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 64380.75
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.

Let's proceed to step 9:
8 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 64380.75
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.

Let's proceed to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 64380.75
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.

The final result is 64380.75 with a remainder of 0.0.
