We divide 339241 by 84
We want to divide 339241 by 84.

Moving 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.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 84

Going ahead to step 2:
33 divided by 84 is 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 84

Moving on to step 3:
The number 84 fits into 339 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 336 from 339, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 84

Going ahead to step 4:
If we divide 32 by 84, we get 0 and a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 32 and we're left with 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 84

Going ahead to step 5:
324 divided by 84 is 3 with a remainder of 72.
The next digit of our result is 3. 
Result so far: 403.0
Subtracting 252 from 324 leaves us with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 84

Let's proceed to step 6:
84 goes into 721 8 times with a remainder of 49.
The next digit of our result is 8. 
Result so far: 4038.0
Subtracting 672 from 721 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
490 divided by 84 is 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 4038.5
Deduct 420 from 490 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
84 goes into 700 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 4038.58
If we take 672 away from 700, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
84 can be fit into 280 3 times, resulting in a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 4038.583
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
280 divided by 84 is 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 4038.5833
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 4038.5833 with a remaining 0.00028.
