Let's divide 374247 by 12
Our goal is to divide 374247 by 12.

Moving on to step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 12

On to step 2:
37 divided by 12 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 1 after subtracting 36 from 37.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 12

Advancing to step 3:
If we divide 14 by 12, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 12 from 14 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 12

On to step 4:
12 can be fit into 22 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 311.0
The remainder is 10 after subtracting 12 from 22.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 12

Moving on to step 5:
When dividing 104 by 12, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 3118.0
The remainder is 8 after subtracting 96 from 104.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 12

Advancing to step 6:
87 divided by 12 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 31187.0
If we subtract 84 from 87, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 31187.2
Subtract 24 from 30 to 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.

Step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 31187.25
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.

Let's proceed to step 9:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31187.25
Subtracting 0 from 0 leaves us with 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:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 31187.25
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 31187.25, with a leftover of 0.0.
