Let's divide 399466 by 84
Let's see how many times 84 fits into 399466.

Advancing to step 1:
3 divided by 84 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 84

On to step 2:
84 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 84

Step 3:
When dividing 399 by 84, we get 4 with a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 336 from 399 leaves us with 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 84

Step 4:
84 goes into 634 7 times with a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Deduct 588 from 634 and we're left with 46.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 84

On to step 5:
The number 84 fits into 466 5 times, leaving a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 475.0
If we take 420 away from 466, we end up with 46.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 84

Going ahead to step 6:
If we divide 466 by 84, we get 5 and a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 4755.0
Deduct 420 from 466 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
460 divided by 84 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 4755.5
Subtract 420 from 460 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
84 can be fit into 400 4 times, resulting in a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 4755.54
Subtract 336 from 400 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
The number 84 fits into 640 7 times, leaving a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 4755.547
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
520 divided by 84 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 4755.5476
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
84 can be fit into 160 1 times, resulting in a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 4755.54761
Subtract 84 from 160 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
When dividing 760 by 84, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 4755.547619
If we take 756 away from 760, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
40 divided by 84 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4755.547619
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
84 goes into 400 4 times with a remainder of 64.
The next digit of our result is 4. 
Result so far: 4755.54761904
Subtracting 336 from 400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 4755.54761904 with a remainder of 6.4e-08.
