We look at the division of 901453 by 2 
The aim is to understand the frequency of 2 in 901453.

Going ahead to step 1:
2 goes into 9 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 1 after subtracting 8 from 9.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Let's proceed to step 2:
When dividing 10 by 2, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 0 after subtracting 10 from 10.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Moving on to step 3:
2 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 450.0
Subtract 0 from 1 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Let's proceed to step 4:
2 goes into 14 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 4507.0
Subtract 14 from 14 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Step 5:
When dividing 5 by 2, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 45072.0
The remainder is 1 after subtracting 4 from 5.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

Advancing to step 6:
When dividing 13 by 2, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 450726.0
Subtract 12 from 13 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.

Let's proceed to step 7:
2 goes into 10 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 450726.5
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.

Let's proceed to step 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 450726.5
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.

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: 450726.5
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 outcome is 450726.5, with a leftover of 0.0.
