We're dividing 310843 by 99 
Let's see how many times 99 fits into 310843.

On to step 1:
If we divide 3 by 99, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 99

On to step 2:
31 divided by 99 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 99

Moving on to step 3:
99 goes into 310 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 297 away from 310, we end up with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 99

On to step 4:
138 divided by 99 is 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 39 after subtracting 99 from 138.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 99

Step 5:
99 can be fit into 394 3 times, resulting in a remainder of 97.
The next digit of our result is 3. 
Result so far: 313.0
If we take 297 away from 394, we end up with 97.
Fetch the next digit (3) from the dividend, attach it to 97 and continue: 973 / 99

Advancing to step 6:
99 can be fit into 973 9 times, resulting in a remainder of 82.
Write down 9 as next digit of the result. 
Result so far: 3139.0
The remainder is 82 after subtracting 891 from 973.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 7:
If we divide 820 by 99, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 3139.8
Deduct 792 from 820 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
The number 99 fits into 280 2 times, leaving a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 3139.82
The remainder is 82 after subtracting 198 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
820 divided by 99 is 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 3139.828
Deduct 792 from 820 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
280 divided by 99 is 2 with a remainder of 82.
The next digit of our result is 2. 
Result so far: 3139.8282
Subtracting 198 from 280 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 11:
If we divide 820 by 99, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 3139.82828
Deduct 792 from 820 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
If we divide 280 by 99, we get 2 and a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 3139.828282
Deduct 198 from 280 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 13:
If we divide 820 by 99, we get 8 and a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 3139.8282828
The remainder is 28 after subtracting 792 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
If we divide 280 by 99, we get 2 and a remainder of 82.
Write down 2 as next digit of the result. 
Result so far: 3139.82828282
The remainder is 82 after subtracting 198 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

After the division, we end up with 3139.82828282 and a remainder of 8.2e-08.
