Let's divide 315499 by 99
We want to divide 315499 by 99.

Let's proceed to step 1:
If we divide 3 by 99, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 99

Moving on to step 2:
If we divide 31 by 99, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 99

Moving on to step 3:
315 divided by 99 is 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 297 from 315 to get 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 99

Advancing to step 4:
The number 99 fits into 184 1 times, leaving a remainder of 85.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 99 from 184 to get 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 99

Step 5:
99 goes into 859 8 times with a remainder of 67.
Put 8 as the next digit of the answer. 
Result so far: 318.0
Subtracting 792 from 859 leaves us with 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 99

Moving on to step 6:
99 goes into 679 6 times with a remainder of 85.
Write down 6 as next digit of the result. 
Result so far: 3186.0
Subtracting 594 from 679 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 7:
If we divide 850 by 99, we get 8 and a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 3186.8
Subtract 792 from 850 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
99 can be fit into 580 5 times, resulting in a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 3186.85
If we take 495 away from 580, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 9:
99 goes into 850 8 times with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 3186.858
If we subtract 792 from 850, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
When dividing 580 by 99, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 3186.8585
The remainder is 85 after subtracting 495 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 11:
850 divided by 99 is 8 with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 3186.85858
The remainder is 58 after subtracting 792 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
The number 99 fits into 580 5 times, leaving a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 3186.858585
Deduct 495 from 580 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 13:
99 goes into 850 8 times with a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 3186.8585858
Subtracting 792 from 850 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 14:
When dividing 580 by 99, we get 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 3186.85858585
If we subtract 495 from 580, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Our division results in 3186.85858585 with a remaining 8.5e-08.
