357449 divided by 12 
We want to figure out the number of times 357449 can be divided by 12.

Let's proceed to step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 12

Step 2:
If we divide 35 by 12, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
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

Moving on to step 3:
The number 12 fits into 117 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 108 from 117, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 12

Let's proceed to step 4:
The number 12 fits into 94 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 297.0
The remainder is 10 after subtracting 84 from 94.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 12

Advancing to step 5:
The number 12 fits into 104 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 2978.0
If we take 96 away from 104, we end up with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 12

Going ahead to step 6:
89 divided by 12 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 29787.0
If we take 84 away from 89, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 12, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 29787.4
If we take 48 away from 50, we end up 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.

On to step 8:
12 goes into 20 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 29787.41
Subtract 12 from 20 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.

Going ahead to step 9:
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: 29787.416
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.

Moving on to step 10:
80 divided by 12 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 29787.4166
If we take 72 away from 80, we end up 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 final outcome is 29787.4166, with a leftover of 8e-05.
