650921 ÷ 2 
The aim is to understand the frequency of 2 in 650921.

Let's proceed to step 1:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 6 from 6 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Step 2:
5 divided by 2 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Deduct 4 from 5 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Let's proceed to step 3:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 325.0
If we subtract 10 from 10, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

On to step 4:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 3254.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

Advancing to step 5:
When dividing 12 by 2, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 32546.0
Subtracting 12 from 12 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Step 6:
When dividing 1 by 2, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 325460.0
Subtracting 0 from 1 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.

Step 7:
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: 325460.5
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.

On to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 325460.5
Deduct 0 from 0 and we're left 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:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 325460.5
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 325460.5, and the remainder is 0.0.
