We look at the division of 290866 by 12 
Our goal is to divide 290866 by 12.

Let's proceed to step 1:
12 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 12

Step 2:
If we divide 29 by 12, we get 2 and a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 24 from 29 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 12

Moving on to step 3:
50 divided by 12 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 48 away from 50, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 12

On to step 4:
When dividing 28 by 12, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 242.0
Deduct 24 from 28 and we're left with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 12

Step 5:
46 divided by 12 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 2423.0
If we take 36 away from 46, we end up with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 12

On to step 6:
When dividing 106 by 12, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 24238.0
If we subtract 96 from 106, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 24238.8
Subtract 96 from 100 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.

Let's proceed to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 24238.83
If we take 36 away from 40, we end up 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 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 24238.833
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.

In conclusion, the division gives 24238.833 with a balance of 0.0004.
