138855 ÷ 99 
We want to figure out the number of times 138855 can be divided by 99.

Advancing to step 1:
1 divided by 99 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
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 / 99

Let's proceed to step 2:
If we divide 13 by 99, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 99

Advancing to step 3:
99 goes into 138 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 99 from 138 to get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 99

Let's proceed to step 4:
99 goes into 398 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 396 from 398 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 99

Step 5:
25 divided by 99 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 99

Step 6:
When dividing 255 by 99, we get 2 with a remainder of 57.
Write down 2 as next digit of the result. 
Result so far: 1402.0
The remainder is 57 after subtracting 198 from 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
When dividing 570 by 99, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 1402.5
If we subtract 495 from 570, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 8:
The number 99 fits into 750 7 times, leaving a remainder of 57.
The next digit of our result is 7. 
Result so far: 1402.57
The remainder is 57 after subtracting 693 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
When dividing 570 by 99, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 1402.575
Subtracting 495 from 570 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 10:
If we divide 750 by 99, we get 7 and a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 1402.5757
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 11:
99 goes into 570 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 1402.57575
Subtract 495 from 570 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
99 goes into 750 7 times with a remainder of 57.
The next digit of our result is 7. 
Result so far: 1402.575757
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 13:
99 can be fit into 570 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 1402.5757575
Subtract 495 from 570 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
If we divide 750 by 99, we get 7 and a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 1402.57575757
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Our division results in 1402.57575757 with a remaining 5.7e-08.
