303513 ÷ 83 
We want to divide 303513 by 83.

Let's proceed to step 1:
The number 83 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 83

Advancing to step 2:
If we divide 30 by 83, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 83

Moving on to step 3:
When dividing 303 by 83, we get 3 with a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 249 from 303, we get 54.
Include the next digit (5) from the dividend after 54, then repeat: 545 / 83

Going ahead to step 4:
83 goes into 545 6 times with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 498 from 545 to get 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 83

Moving on to step 5:
471 divided by 83 is 5 with a remainder of 56.
Use 5 as the next digit of our solution. 
Result so far: 365.0
If we subtract 415 from 471, we get 56.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 83

On to step 6:
83 can be fit into 563 6 times, resulting in a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 3656.0
If we subtract 498 from 563, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 7:
83 goes into 650 7 times with a remainder of 69.
The next digit of our result is 7. 
Result so far: 3656.7
Subtracting 581 from 650 leaves us 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.

Let's proceed to step 8:
When dividing 690 by 83, we get 8 with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 3656.78
If we take 664 away from 690, we end up 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.

Going ahead to step 9:
260 divided by 83 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3656.783
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.

Going ahead to step 10:
83 goes into 110 1 times with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 3656.7831
The remainder is 27 after subtracting 83 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
If we divide 270 by 83, we get 3 and a remainder of 21.
The next digit of our result is 3. 
Result so far: 3656.78313
The remainder is 21 after subtracting 249 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 12:
When dividing 210 by 83, we get 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 3656.783132
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.

Step 13:
If we divide 440 by 83, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3656.7831325
If we take 415 away from 440, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
When dividing 250 by 83, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3656.78313253
Subtracting 249 from 250 leaves us 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.

The final outcome is 3656.78313253, with a leftover of 1e-09.
