12221709 ÷ 2 
Let's see how many times 2 fits into 12221709.

Let's proceed to step 1:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

Step 2:
2 can be fit into 12 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 12 from 12, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

Let's proceed to step 3:
2 divided by 2 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 61.0
Subtracting 2 from 2 leaves us with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

Advancing to step 4:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 611.0
Subtracting 2 from 2 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Let's proceed to step 5:
If we divide 1 by 2, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 6110.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

Going ahead to step 6:
2 goes into 17 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 61108.0
The remainder is 1 after subtracting 16 from 17.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Advancing to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 611085.0
The remainder is 0 after subtracting 10 from 10.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Step 8:
2 goes into 9 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 6110854.0
Subtracting 8 from 9 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.

Moving on to step 9:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6110854.5
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.

Step 10:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6110854.5
Subtract 0 from 0 to 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.

Let's proceed to step 11:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6110854.5
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.

The final result is 6110854.5 with a remainder of 0.0.
