303403 ÷ 83 
Our goal is to divide 303403 by 83.

On to step 1:
If we divide 3 by 83, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 83

Step 2:
30 divided by 83 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 83

Step 3:
303 divided by 83 is 3 with a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 249 away from 303, we end up with 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 83

On to step 4:
83 goes into 544 6 times with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtracting 498 from 544 leaves us with 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 83

Going ahead to step 5:
460 divided by 83 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 365.0
Subtracting 415 from 460 leaves us with 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 83

Step 6:
The number 83 fits into 453 5 times, leaving a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 3655.0
The remainder is 38 after subtracting 415 from 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
83 goes into 380 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 3655.4
The remainder is 48 after subtracting 332 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
When dividing 480 by 83, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 3655.45
If we take 415 away from 480, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
650 divided by 83 is 7 with a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 3655.457
Deduct 581 from 650 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 10:
When dividing 690 by 83, we get 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 3655.4578
Deduct 664 from 690 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.

Let's proceed to step 11:
The number 83 fits into 260 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3655.45783
If we take 249 away from 260, we end up 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.

On to step 12:
When dividing 110 by 83, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 3655.457831
Deduct 83 from 110 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 13:
If we divide 270 by 83, we get 3 and a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3655.4578313
Deduct 249 from 270 and we're left 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.

Let's proceed to step 14:
When dividing 210 by 83, we get 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 3655.45783132
Deduct 166 from 210 and we're left 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.

The quotient of the division is 3655.45783132, and the remainder is 4.4e-08.
