120111 ÷ 1 
We want to divide 120111 by 1.

Step 1:
When dividing 1 by 1, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 1 from 1 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Moving on to step 2:
If we divide 2 by 1, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 2 from 2 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Let's proceed to step 3:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtract 0 from 0 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

On to step 4:
1 divided by 1 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1201.0
If we subtract 1 from 1, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Let's proceed to step 5:
1 divided by 1 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 12011.0
If we subtract 1 from 1, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Let's proceed to step 6:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 120111.0
Subtract 1 from 1 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.

Going ahead to step 7:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 120111.0
If we subtract 0 from 0, we 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.

On to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 120111.0
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.

After the division, we end up with 120111.0 and a remainder of 0.0.
