12312549 divided by 353 
We want to figure out the number of times 12312549 can be divided by 353.

Let's proceed to step 1:
353 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 353

On to step 2:
353 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 353

On to step 3:
The number 353 fits into 123 0 times, leaving a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 123 leaves us with 123.
Grab the next digit (1) from the dividend, add it to 123, then carry on: 1231 / 353

Moving on to step 4:
When dividing 1231 by 353, we get 3 with a remainder of 172.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 172 after subtracting 1059 from 1231.
Grab the next digit (2) from the dividend, add it to 172, then carry on: 1722 / 353

Moving on to step 5:
The number 353 fits into 1722 4 times, leaving a remainder of 310.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 310 after subtracting 1412 from 1722.
Take the next digit (5) from the dividend and append it to 310, then repeat: 3105 / 353

Advancing to step 6:
The number 353 fits into 3105 8 times, leaving a remainder of 281.
Write down 8 as next digit of the result. 
Result so far: 348.0
Subtract 2824 from 3105 to get 281.
Grab the next digit (4) from the dividend, add it to 281, then carry on: 2814 / 353

Going ahead to step 7:
353 can be fit into 2814 7 times, resulting in a remainder of 343.
Use 7 as the next digit of our solution. 
Result so far: 3487.0
The remainder is 343 after subtracting 2471 from 2814.
Fetch the next digit (9) from the dividend, attach it to 343 and continue: 3439 / 353

Moving on to step 8:
If we divide 3439 by 353, we get 9 and a remainder of 262.
Write down 9 as next digit of the result. 
Result so far: 34879.0
If we subtract 3177 from 3439, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 9:
2620 divided by 353 is 7 with a remainder of 149.
The next digit of our result is 7. 
Result so far: 34879.7
If we take 2471 away from 2620, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 10:
When dividing 1490 by 353, we get 4 with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 34879.74
The remainder is 78 after subtracting 1412 from 1490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 11:
353 goes into 780 2 times with a remainder of 74.
Put 2 as the next digit of the answer. 
Result so far: 34879.742
If we take 706 away from 780, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 12:
If we divide 740 by 353, we get 2 and a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 34879.7422
Subtracting 706 from 740 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 34879.7422 with a remainder of 0.00034.
