We're dividing 495807 by 2 
The aim is to understand the frequency of 2 in 495807.

Advancing to step 1:
When dividing 4 by 2, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Step 2:
2 goes into 9 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 1 after subtracting 8 from 9.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

On to step 3:
2 can be fit into 15 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 247.0
If we take 14 away from 15, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Going ahead to step 4:
18 divided by 2 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 2479.0
Deduct 18 from 18 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Moving on to step 5:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 24790.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 2

Advancing to step 6:
If we divide 7 by 2, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 247903.0
Subtract 6 from 7 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 247903.5
If we subtract 10 from 10, 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.

Let's proceed to step 8:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 247903.5
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.

Advancing to step 9:
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: 247903.5
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 247903.5 with a remainder of 0.0.
