We divide 549786 by 2
The aim is to understand the frequency of 2 in 549786.

Let's proceed to step 1:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 4 from 5 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Advancing to step 2:
14 divided by 2 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 0 after subtracting 14 from 14.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Let's proceed to step 3:
If we divide 9 by 2, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 274.0
Subtracting 8 from 9 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 2

Advancing to step 4:
The number 2 fits into 17 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 2748.0
If we subtract 16 from 17, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Let's proceed to step 5:
18 divided by 2 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 27489.0
Deduct 18 from 18 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Moving on to step 6:
The number 2 fits into 6 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 274893.0
If we subtract 6 from 6, 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.

Going ahead to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 274893.0
Subtracting 0 from 0 leaves us 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 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 274893.0
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.

In conclusion, the division gives 274893.0 with a balance of 0.0.
