841420 divided by 2 
The aim is to understand the frequency of 2 in 841420.

On to step 1:
8 divided by 2 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 8 from 8 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

Moving on to step 2:
When dividing 4 by 2, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Advancing to step 3:
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: 420.0
If we subtract 0 from 1, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 2

Advancing to step 4:
14 divided by 2 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 4207.0
Deduct 14 from 14 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Going ahead to step 5:
2 divided by 2 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 42071.0
If we take 2 away from 2, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Going ahead to step 6:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 420710.0
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.

On to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 420710.0
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.

Moving on to step 8:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 420710.0
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.

After the division, we end up with 420710.0 and a remainder of 0.0.
