We're dividing 396310 by 99 
Let's see how many times 99 fits into 396310.

Let's proceed to step 1:
99 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 99

Step 2:
99 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 99

Advancing to step 3:
99 goes into 396 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 396 from 396 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 99

Moving on to step 4:
When dividing 3 by 99, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 99

Let's proceed to step 5:
31 divided by 99 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 400.0
Subtract 0 from 31 to get 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 99

Moving on to step 6:
If we divide 310 by 99, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 4003.0
Subtract 297 from 310 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
If we divide 130 by 99, we get 1 and a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 4003.1
If we subtract 99 from 130, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 8:
310 divided by 99 is 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 4003.13
If we subtract 297 from 310, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
When dividing 130 by 99, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 4003.131
If we subtract 99 from 130, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 10:
99 can be fit into 310 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 4003.1313
Subtracting 297 from 310 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
99 can be fit into 130 1 times, resulting in a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 4003.13131
If we subtract 99 from 130, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 12:
99 goes into 310 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 4003.131313
Subtracting 297 from 310 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
99 can be fit into 130 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 4003.1313131
Deduct 99 from 130 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 14:
99 goes into 310 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 4003.13131313
The remainder is 13 after subtracting 297 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 4003.13131313 with a balance of 1.3e-08.
