282138 divided by 12 
Our goal is to divide 282138 by 12.

On to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 12

Moving on to step 2:
28 divided by 12 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 24 away from 28, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 12

Moving on to step 3:
42 divided by 12 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 36 from 42 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 12

Step 4:
12 can be fit into 61 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 235.0
Subtract 60 from 61 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 12

On to step 5:
When dividing 13 by 12, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 2351.0
If we subtract 12 from 13, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 12

Step 6:
18 divided by 12 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 23511.0
If we take 12 away from 18, 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.

On to step 7:
When dividing 60 by 12, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 23511.5
If we subtract 60 from 60, 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.

Step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 23511.5
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.

Advancing to step 9:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23511.5
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.

After the division, we end up with 23511.5 and a remainder of 0.0.
