We divide 312980 by 83
We want to divide 312980 by 83.

Going ahead to 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
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 83

On to step 2:
31 divided by 83 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 83

Step 3:
When dividing 312 by 83, we get 3 with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 249 from 312 to get 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 83

Step 4:
639 divided by 83 is 7 with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 581 from 639 to get 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 83

Let's proceed to step 5:
83 goes into 588 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 377.0
If we subtract 581 from 588, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 83

Let's proceed to step 6:
83 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 3770.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 7:
The number 83 fits into 700 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 3770.8
Deduct 664 from 700 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
When dividing 360 by 83, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 3770.84
Deduct 332 from 360 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
When dividing 280 by 83, we get 3 with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 3770.843
If we take 249 away from 280, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 10:
When dividing 310 by 83, we get 3 with a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 3770.8433
The remainder is 61 after subtracting 249 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 3770.8433 and a remainder of 0.00061.
