300273 ÷ 84 
Our goal is to divide 300273 by 84.

Step 1:
The number 84 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 84

Going ahead to step 2:
If we divide 30 by 84, we get 0 and 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.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 84

Moving on to step 3:
When dividing 300 by 84, we get 3 with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 48 after subtracting 252 from 300.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 84

Advancing to step 4:
84 goes into 482 5 times with a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 420 away from 482, we end up with 62.
Bring next digit (7) of the dividend behind the 62 and repeat the process: 627 / 84

Going ahead to step 5:
84 goes into 627 7 times with a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 357.0
Deduct 588 from 627 and we're left with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 84

Let's proceed to step 6:
84 goes into 393 4 times with a remainder of 57.
Use 4 as the next digit of our solution. 
Result so far: 3574.0
The remainder is 57 after subtracting 336 from 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
The number 84 fits into 570 6 times, leaving a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 3574.6
The remainder is 66 after subtracting 504 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
84 can be fit into 660 7 times, resulting in a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 3574.67
If we take 588 away from 660, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
If we divide 720 by 84, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 3574.678
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 3574.6785
Subtracting 420 from 480 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
84 can be fit into 600 7 times, resulting in a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 3574.67857
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
The number 84 fits into 120 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 3574.678571
Subtracting 84 from 120 leaves us 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 13:
84 can be fit into 360 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 3574.6785714
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
84 goes into 240 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 3574.67857142
If we take 168 away from 240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 3574.67857142 with a remaining 7.2e-08.
