We're dividing 408063 by 84 
Let's see how many times 84 fits into 408063.

On to step 1:
84 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 84

Advancing to step 2:
If we divide 40 by 84, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 84

Advancing to step 3:
If we divide 408 by 84, we get 4 and a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 336 away from 408, we end up with 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 84

Let's proceed to step 4:
If we divide 720 by 84, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 48.0
If we take 672 away from 720, we end up with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 84

Going ahead to step 5:
486 divided by 84 is 5 with a remainder of 66.
Put 5 as the next digit of the answer. 
Result so far: 485.0
If we subtract 420 from 486, we get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 84

Moving on to step 6:
When dividing 663 by 84, we get 7 with a remainder of 75.
The next digit of our result is 7. 
Result so far: 4857.0
The remainder is 75 after subtracting 588 from 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 7:
If we divide 750 by 84, we get 8 and a remainder of 78.
The next digit of our result is 8. 
Result so far: 4857.8
Subtract 672 from 750 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 8:
If we divide 780 by 84, we get 9 and a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 4857.89
Subtract 756 from 780 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.

Going ahead to step 9:
240 divided by 84 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 4857.892
Deduct 168 from 240 and we're left 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 10:
84 goes into 720 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 4857.8928
Subtracting 672 from 720 leaves us 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.

On to step 11:
84 goes into 480 5 times with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 4857.89285
Deduct 420 from 480 and we're left 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.

Advancing to step 12:
600 divided by 84 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 4857.892857
Subtracting 588 from 600 leaves us 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.

Moving on to step 13:
If we divide 120 by 84, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 4857.8928571
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.

Advancing to step 14:
360 divided by 84 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 4857.89285714
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.

The final result is 4857.89285714 with a remainder of 2.4e-08.
