We're dividing 311390 by 83 
We want to divide 311390 by 83.

Let's proceed to step 1:
When dividing 3 by 83, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 83

On to step 2:
The number 83 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 83

On to step 3:
83 goes into 311 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 62 after subtracting 249 from 311.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 83

Step 4:
83 goes into 623 7 times with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 581 from 623, we get 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 83

Advancing to step 5:
429 divided by 83 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 375.0
Subtract 415 from 429 to get 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 83

Moving on to step 6:
140 divided by 83 is 1 with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 3751.0
If we take 83 away from 140, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
570 divided by 83 is 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 3751.6
If we subtract 498 from 570, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 8:
720 divided by 83 is 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 3751.68
If we subtract 664 from 720, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
83 goes into 560 6 times with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 3751.686
Subtracting 498 from 560 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
The number 83 fits into 620 7 times, leaving a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 3751.6867
Deduct 581 from 620 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
The number 83 fits into 390 4 times, leaving a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 3751.68674
Deduct 332 from 390 and we're left 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.

Let's proceed to step 12:
When dividing 580 by 83, we get 6 with a remainder of 82.
The next digit of our result is 6. 
Result so far: 3751.686746
The remainder is 82 after subtracting 498 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 13:
When dividing 820 by 83, we get 9 with a remainder of 73.
Write down 9 as next digit of the result. 
Result so far: 3751.6867469
Deduct 747 from 820 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 14:
If we divide 730 by 83, we get 8 and a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 3751.68674698
Subtracting 664 from 730 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 3751.68674698 with a remainder of 6.6e-08.
