Let's divide 394255 by 84
We're looking to find how many times 84 goes into 394255.

On to step 1:
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: 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

On to step 2:
84 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 84

Going ahead to step 3:
84 can be fit into 394 4 times, resulting in a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 336 from 394 to get 58.
Bring next digit (2) of the dividend behind the 58 and repeat the process: 582 / 84

Advancing to step 4:
84 can be fit into 582 6 times, resulting in a remainder of 78.
The next digit of our result is 6. 
Result so far: 46.0
Subtract 504 from 582 to get 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 84

Let's proceed to step 5:
84 can be fit into 785 9 times, resulting in a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 469.0
The remainder is 29 after subtracting 756 from 785.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 84

Moving on to step 6:
If we divide 295 by 84, we get 3 and a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 4693.0
Subtracting 252 from 295 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
The number 84 fits into 430 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 4693.5
The remainder is 10 after subtracting 420 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 84, we get 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 4693.51
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
160 divided by 84 is 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 4693.511
If we take 84 away from 160, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 4693.511, with a leftover of 0.0076.
