We look at the division of 285149 by 12 
Our goal is to divide 285149 by 12.

Moving on to step 1:
2 divided by 12 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
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

Let's proceed to step 2:
12 can be fit into 28 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 24 from 28 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 12

On to step 3:
The number 12 fits into 45 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 36 from 45 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 12

Step 4:
91 divided by 12 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 237.0
The remainder is 7 after subtracting 84 from 91.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 12

Step 5:
The number 12 fits into 74 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 2376.0
Subtracting 72 from 74 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 12

Let's proceed to step 6:
12 goes into 29 2 times with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 23762.0
Deduct 24 from 29 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
50 divided by 12 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 23762.4
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
12 goes into 20 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 23762.41
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 23762.416
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
12 goes into 80 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 23762.4166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 23762.4166 with a remaining 8e-05.
