Let's divide 661949 by 2
The aim is to understand the frequency of 2 in 661949.

Going ahead to step 1:
2 goes into 6 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 6 away from 6, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

On to step 2:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 33.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

On to step 3:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 330.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Advancing to step 4:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 3309.0
If we subtract 18 from 19, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

Moving on to step 5:
2 goes into 14 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 33097.0
The remainder is 0 after subtracting 14 from 14.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Advancing to step 6:
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: 330974.0
Subtract 8 from 9 to get 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:
When dividing 10 by 2, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 330974.5
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.

Going ahead to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 330974.5
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.

Moving on to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 330974.5
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 quotient of the division is 330974.5, and the remainder is 0.0.
