We're dividing 357360 by 12 
We're looking to find how many times 12 goes into 357360.

Let's proceed to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 12

Advancing to step 2:
The number 12 fits into 35 2 times, leaving a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 24 from 35, we get 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 12

On to step 3:
12 can be fit into 117 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 108 from 117 leaves us with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 12

Let's proceed to step 4:
The number 12 fits into 93 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 297.0
Subtract 84 from 93 to get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 12

Moving on to step 5:
If we divide 96 by 12, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 2978.0
If we subtract 96 from 96, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 12

Let's proceed to step 6:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 29780.0
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.

On to step 7:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29780.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 29780.0
Deduct 0 from 0 and we're left 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.

Our division results in 29780.0 with a remaining 0.0.
