312158 divided by 83 
We want to divide 312158 by 83.

Step 1:
If we divide 3 by 83, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 83

Step 2:
The number 83 fits into 31 0 times, leaving 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.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 83

On to step 3:
83 goes into 312 3 times with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 249 from 312 to get 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 83

Advancing to step 4:
When dividing 631 by 83, we get 7 with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 581 from 631 to get 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 83

Step 5:
83 goes into 505 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 376.0
Subtract 498 from 505 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 83

On to step 6:
83 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 3760.0
Deduct 0 from 78 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 7:
If we divide 780 by 83, we get 9 and a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 3760.9
Deduct 747 from 780 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 8:
83 goes into 330 3 times with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 3760.93
The remainder is 81 after subtracting 249 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
810 divided by 83 is 9 with a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 3760.939
If we subtract 747 from 810, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 10:
83 can be fit into 630 7 times, resulting in a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 3760.9397
Deduct 581 from 630 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 11:
83 can be fit into 490 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 3760.93975
If we subtract 415 from 490, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 12:
83 can be fit into 750 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 3760.939759
Deduct 747 from 750 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
83 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 3760.939759
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
The number 83 fits into 300 3 times, leaving a remainder of 51.
The next digit of our result is 3. 
Result so far: 3760.93975903
Subtract 249 from 300 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 3760.93975903 and a remainder of 5.1e-08.
