Let's divide 398280 by 84
Let's see how many times 84 fits into 398280.

Let's proceed to step 1:
84 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 84

Step 2:
84 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 84

Going ahead to step 3:
The number 84 fits into 398 4 times, leaving a remainder of 62.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 336 from 398, we get 62.
Append the next digit (2) from the dividend to 62 and continue with: 622 / 84

Moving on to step 4:
When dividing 622 by 84, we get 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 47.0
If we take 588 away from 622, we end up with 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 84

On to step 5:
84 goes into 348 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 474.0
If we subtract 336 from 348, we get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 84

On to step 6:
120 divided by 84 is 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 4741.0
If we subtract 84 from 120, we get 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 7:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 4741.4
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
84 goes into 240 2 times with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 4741.42
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
The number 84 fits into 720 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 4741.428
If we take 672 away from 720, we end up with 48.
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 10:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 4741.4285
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.

Going ahead to step 11:
600 divided by 84 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 4741.42857
If we take 588 away from 600, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
84 goes into 120 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 4741.428571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 4741.4285714
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
When dividing 240 by 84, we get 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 4741.42857142
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.

The final result is 4741.42857142 with a remainder of 7.2e-08.
