Let's divide 351555 by 12
We're looking to find how many times 12 goes into 351555.

On to step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 12

Going ahead to step 2:
The number 12 fits into 35 2 times, leaving a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 11 after subtracting 24 from 35.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 12

Advancing to step 3:
When dividing 111 by 12, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 108 from 111 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 12

Going ahead to step 4:
35 divided by 12 is 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 292.0
Subtract 24 from 35 to get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 12

Let's proceed to step 5:
The number 12 fits into 115 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 2929.0
Deduct 108 from 115 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 12

Going ahead to step 6:
When dividing 75 by 12, we get 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 29296.0
If we take 72 away from 75, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 29296.2
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.

Moving on to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 29296.25
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:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 29296.25
Subtract 0 from 0 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.

Step 10:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 29296.25
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.

In conclusion, the division gives 29296.25 with a balance of 0.0.
