12899 ÷ 83 
Our goal is to divide 12899 by 83.

Advancing to step 1:
1 divided by 83 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 83

Going ahead to step 2:
If we divide 12 by 83, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 83

Step 3:
The number 83 fits into 128 1 times, leaving a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 83 from 128 leaves us with 45.
Take the next digit (9) from the dividend and append it to 45, then repeat: 459 / 83

Step 4:
If we divide 459 by 83, we get 5 and a remainder of 44.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 415 from 459, we get 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 83

Moving on to step 5:
If we divide 449 by 83, we get 5 and a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Subtracting 415 from 449 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.

Moving on to step 6:
83 can be fit into 340 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 155.4
If we take 332 away from 340, 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.

Moving on to step 7:
83 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 155.4
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 8:
83 goes into 800 9 times with a remainder of 53.
The next digit of our result is 9. 
Result so far: 155.409
The remainder is 53 after subtracting 747 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 9:
When dividing 530 by 83, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 155.4096
The remainder is 32 after subtracting 498 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
83 can be fit into 320 3 times, resulting in a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 155.40963
Subtract 249 from 320 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 11:
When dividing 710 by 83, we get 8 with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 155.409638
The remainder is 46 after subtracting 664 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
460 divided by 83 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 155.4096385
The remainder is 45 after subtracting 415 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
83 can be fit into 450 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 155.40963855
If we subtract 415 from 450, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 155.40963855 with a remaining 3.5e-08.
