We divide 121720 by 2
We're looking to find how many times 2 goes into 121720.

Moving on to step 1:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

Step 2:
2 can be fit into 12 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 0 after subtracting 12 from 12.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Going ahead to step 3:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

Let's proceed to step 4:
If we divide 17 by 2, we get 8 and a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 608.0
Subtracting 16 from 17 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Let's proceed to step 5:
The number 2 fits into 12 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6086.0
If we subtract 12 from 12, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Advancing to step 6:
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: 60860.0
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.

Advancing to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 60860.0
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.

Step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 60860.0
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.

Our division results in 60860.0 with a remaining 0.0.
