285300 ÷ 83 
We want to divide 285300 by 83.

On to step 1:
If we divide 2 by 83, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 83

Let's proceed to step 2:
The number 83 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 83

Advancing to step 3:
83 goes into 285 3 times with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 249 from 285 to get 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 83

Let's proceed to step 4:
When dividing 363 by 83, we get 4 with a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 332 from 363 to get 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 83

Step 5:
When dividing 310 by 83, we get 3 with a remainder of 61.
The next digit of our result is 3. 
Result so far: 343.0
Subtracting 249 from 310 leaves us with 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 83

Advancing to step 6:
When dividing 610 by 83, we get 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 3437.0
Deduct 581 from 610 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
If we divide 290 by 83, we get 3 and a remainder of 41.
The next digit of our result is 3. 
Result so far: 3437.3
If we take 249 away from 290, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 8:
If we divide 410 by 83, we get 4 and a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 3437.34
Subtracting 332 from 410 leaves us 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.

On to step 9:
780 divided by 83 is 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 3437.349
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.

Step 10:
330 divided by 83 is 3 with a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 3437.3493
If we take 249 away from 330, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 11:
810 divided by 83 is 9 with a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 3437.34939
Subtracting 747 from 810 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 12:
83 goes into 630 7 times with a remainder of 49.
The next digit of our result is 7. 
Result so far: 3437.349397
The remainder is 49 after subtracting 581 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 13:
The number 83 fits into 490 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 3437.3493975
Subtract 415 from 490 to 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.

Step 14:
83 goes into 750 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 3437.34939759
If we subtract 747 from 750, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 3437.34939759 with a remainder of 3e-09.
