Let's divide 268890 by 12
We want to divide 268890 by 12.

Advancing to step 1:
12 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 12

Going ahead to step 2:
26 divided by 12 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 24 from 26 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 12

Let's proceed to step 3:
12 can be fit into 28 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 4 after subtracting 24 from 28.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 12

Let's proceed to step 4:
When dividing 48 by 12, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 224.0
Subtract 48 from 48 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 12

Let's proceed to step 5:
12 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 2240.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 12

Step 6:
90 divided by 12 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 22407.0
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 22407.5
Subtract 60 from 60 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 8:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22407.5
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.

Advancing to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22407.5
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.

The final outcome is 22407.5, with a leftover of 0.0.
