Let's divide 31819 by 99
We want to divide 31819 by 99.

Let's proceed to step 1:
3 divided by 99 is 0 with 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.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 99

Let's proceed to step 2:
The number 99 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 99

On to step 3:
When dividing 318 by 99, we get 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 297 from 318, we get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 99

Moving on to step 4:
99 can be fit into 211 2 times, resulting in a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
The remainder is 13 after subtracting 198 from 211.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 99

Let's proceed to step 5:
When dividing 139 by 99, we get 1 with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 321.0
If we take 99 away from 139, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 6:
If we divide 400 by 99, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 321.4
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
40 divided by 99 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 321.4
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
If we divide 400 by 99, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 321.404
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
99 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 321.404
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 99 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 321.40404
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
99 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 321.40404
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
99 goes into 400 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 321.4040404
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
99 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 321.4040404
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 321.4040404 with a remaining 4e-08.
