Let's divide 31815 by 83
Our goal is to divide 31815 by 83.

On to step 1:
83 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 83

Going ahead to step 2:
31 divided by 83 is 0 with 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 / 83

Moving on to step 3:
When dividing 318 by 83, we get 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 249 from 318, we get 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 83

Step 4:
If we divide 691 by 83, we get 8 and a remainder of 27.
The next digit of our result is 8. 
Result so far: 38.0
If we subtract 664 from 691, we get 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 83

On to step 5:
The number 83 fits into 275 3 times, leaving a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 383.0
Deduct 249 from 275 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 6:
83 can be fit into 260 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 383.3
Subtracting 249 from 260 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
83 can be fit into 110 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 383.31
If we subtract 83 from 110, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 8:
83 can be fit into 270 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 383.313
If we take 249 away from 270, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
If we divide 210 by 83, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 383.3132
If we take 166 away from 210, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
When dividing 440 by 83, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 383.31325
The remainder is 25 after subtracting 415 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
When dividing 250 by 83, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 383.313253
Deduct 249 from 250 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
83 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 383.313253
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
When dividing 100 by 83, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 383.31325301
The remainder is 17 after subtracting 83 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 383.31325301 with a remainder of 1.7e-08.
