13681079 ÷ 356 
We want to figure out the number of times 13681079 can be divided by 356.

Step 1:
The number 356 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 356

Advancing to step 2:
356 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 356

Moving on to step 3:
The number 356 fits into 136 0 times, leaving a remainder of 136.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 136, we end up with 136.
Grab the next digit (8) from the dividend, add it to 136, then carry on: 1368 / 356

On to step 4:
356 goes into 1368 3 times with a remainder of 300.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 1068 from 1368 leaves us with 300.
Include the next digit (1) from the dividend after 300, then repeat: 3001 / 356

Going ahead to step 5:
3001 divided by 356 is 8 with a remainder of 153.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
The remainder is 153 after subtracting 2848 from 3001.
Bring next digit (0) of the dividend behind the 153 and repeat the process: 1530 / 356

Moving on to step 6:
1530 divided by 356 is 4 with a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 384.0
Subtracting 1424 from 1530 leaves us with 106.
Include the next digit (7) from the dividend after 106, then repeat: 1067 / 356

Step 7:
When dividing 1067 by 356, we get 2 with a remainder of 355.
The number 2 becomes the next digit in our result. 
Result so far: 3842.0
If we take 712 away from 1067, we end up with 355.
Append the next digit (9) from the dividend to 355 and continue with: 3559 / 356

Advancing to step 8:
The number 356 fits into 3559 9 times, leaving a remainder of 355.
The number 9 becomes the next digit in our result. 
Result so far: 38429.0
Deduct 3204 from 3559 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 9:
The number 356 fits into 3550 9 times, leaving a remainder of 346.
Put 9 as the next digit of the answer. 
Result so far: 38429.9
If we subtract 3204 from 3550, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 10:
356 goes into 3460 9 times with a remainder of 256.
The number 9 becomes the next digit in our result. 
Result so far: 38429.99
If we take 3204 away from 3460, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final result is 38429.99 with a remainder of 0.256.
