485985 divided by 2 
The aim is to understand the frequency of 2 in 485985.

Step 1:
When dividing 4 by 2, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 4 from 4, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Advancing to step 2:
When dividing 8 by 2, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 8 from 8 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Going ahead to step 3:
5 divided by 2 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 242.0
Deduct 4 from 5 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

On to step 4:
2 goes into 19 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 2429.0
Subtract 18 from 19 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Moving on to step 5:
If we divide 18 by 2, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 24299.0
The remainder is 0 after subtracting 18 from 18.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Going ahead to step 6:
2 goes into 5 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 242992.0
Deduct 4 from 5 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 242992.5
The remainder is 0 after subtracting 10 from 10.
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:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 242992.5
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:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 242992.5
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.

After the division, we end up with 242992.5 and a remainder of 0.0.
