We look at the division of 492573 by 2 
The aim is to understand the frequency of 2 in 492573.

Going ahead to step 1:
If we divide 4 by 2, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 4 away from 4, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Let's proceed to step 2:
9 divided by 2 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 8 from 9, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

On to step 3:
2 goes into 12 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Subtracting 12 from 12 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Advancing to step 4:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2462.0
If we subtract 4 from 5, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 2

Step 5:
If we divide 17 by 2, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 24628.0
Subtracting 16 from 17 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Advancing to step 6:
2 can be fit into 13 6 times, resulting in a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 246286.0
If we subtract 12 from 13, we 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.

Advancing to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 246286.5
Subtract 10 from 10 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.

On to step 8:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 246286.5
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 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 246286.5
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.

Our division results in 246286.5 with a remaining 0.0.
