We divide 911589 by 2
The aim is to understand the frequency of 2 in 911589.

Step 1:
9 divided by 2 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
If we take 8 away from 9, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

Moving on to step 2:
The number 2 fits into 11 5 times, leaving a remainder of 1.
The next digit of our result is 5. 
Result so far: 45.0
Subtract 10 from 11 to get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Going ahead to step 3:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 455.0
Deduct 10 from 11 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Let's proceed to step 4:
15 divided by 2 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 4557.0
If we subtract 14 from 15, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Advancing to step 5:
2 can be fit into 18 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 45579.0
If we take 18 away from 18, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Moving on to step 6:
If we divide 9 by 2, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 455794.0
If we subtract 8 from 9, 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.

Moving on to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 455794.5
Subtracting 10 from 10 leaves us 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 8:
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: 455794.5
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:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 455794.5
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.

The final result is 455794.5 with a remainder of 0.0.
