490661 divided by 2 
The aim is to understand the frequency of 2 in 490661.

Moving on to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Moving on to step 2:
2 can be fit into 9 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 8 from 9 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Let's proceed to step 3:
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: 245.0
Subtract 10 from 10 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Advancing to step 4:
If we divide 6 by 2, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 2453.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Moving on to step 5:
6 divided by 2 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 24533.0
Subtract 6 from 6 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Going ahead to step 6:
When dividing 1 by 2, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 245330.0
Subtract 0 from 1 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.

Moving on to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 245330.5
If we take 10 away from 10, 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.

Moving on to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 245330.5
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.

On to step 9:
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: 245330.5
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.

After the division, we end up with 245330.5 and a remainder of 0.0.
