We look at the division of 473123 by 2 
The aim is to understand the frequency of 2 in 473123.

On to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 2

Step 2:
When dividing 7 by 2, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 6 away from 7, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 2

Moving on to step 3:
The number 2 fits into 13 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 236.0
If we take 12 away from 13, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Advancing to step 4:
11 divided by 2 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 2365.0
If we subtract 10 from 11, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

Let's proceed to step 5:
The number 2 fits into 12 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 23656.0
If we take 12 away from 12, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Let's proceed to step 6:
If we divide 3 by 2, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 236561.0
Subtracting 2 from 3 leaves us 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:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 236561.5
If we subtract 10 from 10, 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.

Advancing to step 8:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 236561.5
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.

Step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 236561.5
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 236561.5 with a remainder of 0.0.
