We look at the division of 311904 by 99 
Let's see how many times 99 fits into 311904.

Step 1:
99 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in 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

Going ahead to step 2:
31 divided by 99 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 99

On to step 3:
When dividing 311 by 99, we get 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 297 from 311 to get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 99

On to step 4:
99 can be fit into 149 1 times, resulting in a remainder of 50.
The next digit of our result is 1. 
Result so far: 31.0
If we subtract 99 from 149, we get 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 99

Moving on to step 5:
99 goes into 500 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 315.0
Subtract 495 from 500 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 99

On to step 6:
54 divided by 99 is 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 3150.0
If we take 0 away from 54, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
99 goes into 540 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 3150.5
If we subtract 495 from 540, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
When dividing 450 by 99, we get 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 3150.54
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
540 divided by 99 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 3150.545
If we subtract 495 from 540, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
99 can be fit into 450 4 times, resulting in a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 3150.5454
If we take 396 away from 450, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
If we divide 540 by 99, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 3150.54545
Subtracting 495 from 540 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 12:
If we divide 450 by 99, we get 4 and a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 3150.545454
Deduct 396 from 450 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
If we divide 540 by 99, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 3150.5454545
Subtract 495 from 540 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
If we divide 450 by 99, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 3150.54545454
Subtracting 396 from 450 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 3150.54545454, with a leftover of 5.4e-08.
