861277 divided by 2 
The aim is to understand the frequency of 2 in 861277.

On to step 1:
8 divided by 2 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 8 from 8 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Advancing to step 2:
If we divide 6 by 2, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Moving on to step 3:
If we divide 1 by 2, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 430.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Advancing to step 4:
12 divided by 2 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 4306.0
Subtracting 12 from 12 leaves us with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 2

Moving on to step 5:
2 can be fit into 7 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 43063.0
Deduct 6 from 7 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

Advancing to step 6:
If we divide 17 by 2, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 430638.0
If we subtract 16 from 17, we 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.

Advancing to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 430638.5
Deduct 10 from 10 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.

Let's proceed to step 8:
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: 430638.5
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.

Going ahead to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 430638.5
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.

The final result is 430638.5 with a remainder of 0.0.
