We look at the division of 51765240 by 2 
The aim is to understand the frequency of 2 in 51765240.

Going ahead to step 1:
2 can be fit into 5 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 4 away from 5, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Moving on to step 2:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 25.0
The remainder is 1 after subtracting 10 from 11.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

Advancing to step 3:
If we divide 17 by 2, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 258.0
If we subtract 16 from 17, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

Advancing to step 4:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 2588.0
Subtract 16 from 16 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Step 5:
If we divide 5 by 2, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 25882.0
Subtracting 4 from 5 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Let's proceed to step 6:
When dividing 12 by 2, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 258826.0
The remainder is 0 after subtracting 12 from 12.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Let's proceed to step 7:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2588262.0
Subtracting 4 from 4 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Moving on to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25882620.0
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.

On to step 9:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 25882620.0
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.

Let's proceed to step 10:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25882620.0
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.

The final outcome is 25882620.0, with a leftover of 0.0.
