Let's divide 336399 by 84
Our goal is to divide 336399 by 84.

Moving on to step 1:
If we divide 3 by 84, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 84

Moving on to step 2:
If we divide 33 by 84, we get 0 and a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 84

Moving on to step 3:
The number 84 fits into 336 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 336 from 336 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 84

Advancing to step 4:
3 divided by 84 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 84

Moving on to step 5:
When dividing 39 by 84, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 400.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 84

Moving on to step 6:
84 can be fit into 399 4 times, resulting in a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 4004.0
If we subtract 336 from 399, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
84 goes into 630 7 times with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 4004.7
If we subtract 588 from 630, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
84 goes into 420 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 4004.75
The remainder is 0 after subtracting 420 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 84, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4004.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
0 divided by 84 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4004.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 4004.75 with a balance of 0.0.
