We look at the division of 125410 by 2 
The aim is to understand the frequency of 2 in 125410.

On to step 1:
1 divided by 2 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Moving on to step 2:
12 divided by 2 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 12 from 12 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Let's proceed to step 3:
2 goes into 5 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we subtract 4 from 5, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Let's proceed to step 4:
14 divided by 2 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 627.0
If we subtract 14 from 14, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Moving on to step 5:
If we divide 1 by 2, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 6270.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Going ahead to step 6:
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: 62705.0
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.

Let's proceed to step 7:
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: 62705.0
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.

Advancing to step 8:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 62705.0
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 62705.0 with a remainder of 0.0.
