395815 divided by 84 
We want to figure out the number of times 395815 can be divided by 84.

On to step 1:
If we divide 3 by 84, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 84

Moving on to step 2:
84 can be fit into 39 0 times, resulting in 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 (5) of the dividend behind the 39 and repeat the process: 395 / 84

Advancing to step 3:
If we divide 395 by 84, we get 4 and a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 59 after subtracting 336 from 395.
Bring next digit (8) of the dividend behind the 59 and repeat the process: 598 / 84

Let's proceed to step 4:
598 divided by 84 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Deduct 588 from 598 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 84

Going ahead to step 5:
The number 84 fits into 101 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 471.0
If we take 84 away from 101, we end up with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 84

On to step 6:
175 divided by 84 is 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 4712.0
Subtracting 168 from 175 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
84 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 4712.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
84 can be fit into 700 8 times, resulting in a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 4712.08
The remainder is 28 after subtracting 672 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
If we divide 280 by 84, we get 3 and a remainder of 28.
The next digit of our result is 3. 
Result so far: 4712.083
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.

Step 10:
If we divide 280 by 84, we get 3 and a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 4712.0833
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 4712.0833, with a leftover of 0.00028.
