1380 ÷ 99 
We want to figure out the number of times 1380 can be divided by 99.

Going ahead to step 1:
When dividing 1 by 99, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 99

Moving on to step 2:
The number 99 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 99

Moving on to step 3:
138 divided by 99 is 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 99 away from 138, we end up with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 99

Going ahead to step 4:
99 can be fit into 390 3 times, resulting in a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 297 from 390 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 5:
If we divide 930 by 99, we get 9 and a remainder of 39.
The next digit of our result is 9. 
Result so far: 13.9
If we take 891 away from 930, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 6:
99 can be fit into 390 3 times, resulting in a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 13.93
Subtract 297 from 390 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 7:
99 goes into 930 9 times with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 13.939
The remainder is 39 after subtracting 891 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
The number 99 fits into 390 3 times, leaving a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 13.9393
Subtract 297 from 390 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 9:
99 can be fit into 930 9 times, resulting in a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 13.93939
Deduct 891 from 930 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
If we divide 390 by 99, we get 3 and a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 13.939393
If we take 297 away from 390, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 11:
99 goes into 930 9 times with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 13.9393939
If we subtract 891 from 930, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 12:
99 can be fit into 390 3 times, resulting in a remainder of 93.
Put 3 as the next digit of the answer. 
Result so far: 13.93939393
If we take 297 away from 390, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Our division results in 13.93939393 with a remaining 9.3e-08.
