We're dividing 298510 by 12 
Let's see how many times 12 fits into 298510.

Moving on 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
If we subtract 0 from 2, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 12

Going ahead to step 2:
12 can be fit into 29 2 times, resulting in a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 24 from 29 and we're left with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 12

Going ahead to step 3:
58 divided by 12 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 10 after subtracting 48 from 58.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 12

Advancing to step 4:
12 can be fit into 105 8 times, resulting in a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 248.0
If we subtract 96 from 105, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 12

Moving on to step 5:
When dividing 91 by 12, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 2487.0
Subtract 84 from 91 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 12

Let's proceed to step 6:
When dividing 70 by 12, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 24875.0
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 24875.8
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 24875.83
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
12 goes into 40 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 24875.833
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 24875.833, and the remainder is 0.0004.
