290313 divided by 12 
Our goal is to divide 290313 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
Deduct 0 from 2 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 12

Going ahead to step 2:
12 can be fit into 29 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 5 after subtracting 24 from 29.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 12

Advancing to step 3:
If we divide 50 by 12, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 24.0
If we take 48 away from 50, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 12

Step 4:
12 goes into 23 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 241.0
Deduct 12 from 23 and we're left with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 12

Let's proceed to step 5:
The number 12 fits into 111 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 2419.0
Subtract 108 from 111 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 12

Advancing to step 6:
When dividing 33 by 12, we get 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 24192.0
Deduct 24 from 33 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
12 goes into 90 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 24192.7
If we subtract 84 from 90, we get 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 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 24192.75
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 9:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 24192.75
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.

Moving on to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 24192.75
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.

The final outcome is 24192.75, with a leftover of 0.0.
