We divide 390230 by 84
Our goal is to divide 390230 by 84.

Let's proceed 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
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 84

Moving on to step 2:
84 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 84

Moving on to step 3:
If we divide 390 by 84, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 336 from 390 to get 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 84

Going ahead to step 4:
84 can be fit into 542 6 times, resulting in a remainder of 38.
The next digit of our result is 6. 
Result so far: 46.0
If we subtract 504 from 542, we get 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 84

Step 5:
If we divide 383 by 84, we get 4 and a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 464.0
Subtracting 336 from 383 leaves us with 47.
Take the next digit (0) from the dividend and append it to 47, then repeat: 470 / 84

Let's proceed to step 6:
The number 84 fits into 470 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 4645.0
If we take 420 away from 470, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
500 divided by 84 is 5 with a remainder of 80.
The next digit of our result is 5. 
Result so far: 4645.5
Subtract 420 from 500 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
800 divided by 84 is 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 4645.59
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
84 can be fit into 440 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 4645.595
The remainder is 20 after subtracting 420 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
84 goes into 200 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 4645.5952
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
84 can be fit into 320 3 times, resulting in a remainder of 68.
The next digit of our result is 3. 
Result so far: 4645.59523
Subtracting 252 from 320 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 12:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 4645.595238
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
80 divided by 84 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 4645.595238
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
84 can be fit into 800 9 times, resulting in a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 4645.59523809
Subtracting 756 from 800 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 4645.59523809 with a remaining 4.4e-08.
