Let's divide 351890 by 12
Let's see how many times 12 fits into 351890.

Advancing to step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 12

On to step 2:
12 goes into 35 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 11 after subtracting 24 from 35.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 12

Let's proceed to step 3:
111 divided by 12 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 108 from 111, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 12

Going ahead to step 4:
38 divided by 12 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 293.0
The remainder is 2 after subtracting 36 from 38.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 12

Let's proceed to step 5:
29 divided by 12 is 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2932.0
If we take 24 away from 29, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 12

Let's proceed to step 6:
50 divided by 12 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 29324.0
Deduct 48 from 50 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
12 goes into 20 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 29324.1
Subtracting 12 from 20 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 29324.16
Subtract 72 from 80 to 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.

Let's proceed to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 29324.166
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 29324.166, and the remainder is 0.0008.
