Let's divide 121868 by 1
We're looking to find how many times 1 goes into 121868.

Step 1:
1 goes into 1 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 1 from 1, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Let's proceed to step 2:
When dividing 2 by 1, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 2 from 2 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Moving on to step 3:
1 goes into 1 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 1 from 1 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Advancing to step 4:
When dividing 8 by 1, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 1218.0
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 / 1

Step 5:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 12186.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

On to step 6:
1 goes into 8 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 121868.0
If we subtract 8 from 8, 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.

Let's proceed to step 7:
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: 121868.0
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.

Moving on to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 121868.0
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.

After the division, we end up with 121868.0 and a remainder of 0.0.
