Let's divide 543929 by 2
The aim is to understand the frequency of 2 in 543929.

Going ahead to step 1:
When dividing 5 by 2, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 4 from 5 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Advancing to step 2:
The number 2 fits into 14 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 14 from 14 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 2

Let's proceed to step 3:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 271.0
Deduct 2 from 3 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Let's proceed to step 4:
The number 2 fits into 19 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 2719.0
Subtract 18 from 19 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Advancing to step 5:
2 can be fit into 12 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 27196.0
Subtract 12 from 12 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

On to step 6:
9 divided by 2 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 271964.0
Deduct 8 from 9 and we're left 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.

On to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 271964.5
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.

Going ahead to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 271964.5
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:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 271964.5
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.

After the division, we end up with 271964.5 and a remainder of 0.0.
