397647 ÷ 84 
Our goal is to divide 397647 by 84.

Step 1:
84 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 84

Moving on to step 2:
39 divided by 84 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 84

Advancing to step 3:
If we divide 397 by 84, we get 4 and a remainder of 61.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 336 from 397 and we're left with 61.
Grab the next digit (6) from the dividend, add it to 61, then carry on: 616 / 84

Let's proceed to step 4:
616 divided by 84 is 7 with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Deduct 588 from 616 and we're left with 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 84

Step 5:
84 goes into 284 3 times with a remainder of 32.
The next digit of our result is 3. 
Result so far: 473.0
If we subtract 252 from 284, we get 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 84

Let's proceed to step 6:
When dividing 327 by 84, we get 3 with a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 4733.0
The remainder is 75 after subtracting 252 from 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 7:
If we divide 750 by 84, we get 8 and a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 4733.8
Subtracting 672 from 750 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 8:
780 divided by 84 is 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 4733.89
If we subtract 756 from 780, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
If we divide 240 by 84, we get 2 and a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 4733.892
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
If we divide 720 by 84, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 4733.8928
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
When dividing 480 by 84, we get 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 4733.89285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 4733.892857
If we take 588 away from 600, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
When dividing 120 by 84, we get 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 4733.8928571
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
84 goes into 360 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 4733.89285714
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 4733.89285714 and a remainder of 2.4e-08.
