616678 ÷ 2 
The aim is to understand the frequency of 2 in 616678.

Let's proceed to step 1:
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: 3.0
Subtracting 6 from 6 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

On to step 2:
1 divided by 2 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Step 3:
16 divided by 2 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 308.0
If we take 16 away from 16, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Let's proceed to step 4:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3083.0
Subtracting 6 from 6 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Step 5:
7 divided by 2 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 30833.0
The remainder is 1 after subtracting 6 from 7.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Let's proceed to step 6:
If we divide 18 by 2, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 308339.0
The remainder is 0 after subtracting 18 from 18.
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 7:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 308339.0
The remainder is 0 after subtracting 0 from 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:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 308339.0
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 outcome is 308339.0, with a leftover of 0.0.
