Let's divide 305286 by 84
We're looking to find how many times 84 goes into 305286.

On to step 1:
If we divide 3 by 84, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
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 / 84

On to step 2:
The number 84 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 84

Going ahead to step 3:
84 goes into 305 3 times with a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 252 from 305 leaves us with 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 84

Going ahead to step 4:
When dividing 532 by 84, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
The remainder is 28 after subtracting 504 from 532.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 84

Step 5:
288 divided by 84 is 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 363.0
If we subtract 252 from 288, we get 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 84

Let's proceed to step 6:
The number 84 fits into 366 4 times, leaving a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 3634.0
If we subtract 336 from 366, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
300 divided by 84 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 3634.3
If we subtract 252 from 300, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
When dividing 480 by 84, we get 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 3634.35
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 3634.357
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
The number 84 fits into 120 1 times, leaving a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 3634.3571
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.

Moving on to step 11:
360 divided by 84 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 3634.35714
Subtract 336 from 360 to 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 12:
The number 84 fits into 240 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 3634.357142
Subtracting 168 from 240 leaves us 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.

Moving on to step 13:
If we divide 720 by 84, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 3634.3571428
If we subtract 672 from 720, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
84 goes into 480 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 3634.35714285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 3634.35714285 and a remainder of 6e-08.
