512676 ÷ 2 
The aim is to understand the frequency of 2 in 512676.

Advancing to step 1:
The number 2 fits into 5 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 4 from 5 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 2

Step 2:
11 divided by 2 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 10 from 11 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

Let's proceed to step 3:
12 divided by 2 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
Subtracting 12 from 12 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Let's proceed to step 4:
If we divide 6 by 2, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 2563.0
If we subtract 6 from 6, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 2

Going ahead to step 5:
2 goes into 7 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 25633.0
The remainder is 1 after subtracting 6 from 7.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

Step 6:
2 goes into 16 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 256338.0
Subtract 16 from 16 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 7:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 256338.0
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.

Going ahead to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 256338.0
If we take 0 away from 0, we end up 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 outcome is 256338.0, with a leftover of 0.0.
