821984 divided by 84 
Let's see how many times 84 fits into 821984.

On to step 1:
8 divided by 84 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 84

Going ahead to step 2:
84 can be fit into 82 0 times, resulting in a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 84

Let's proceed to step 3:
821 divided by 84 is 9 with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 756 away from 821, we end up with 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 84

Going ahead to step 4:
The number 84 fits into 659 7 times, leaving a remainder of 71.
The next digit of our result is 7. 
Result so far: 97.0
If we subtract 588 from 659, we get 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 84

Let's proceed to step 5:
When dividing 718 by 84, we get 8 with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 978.0
Subtracting 672 from 718 leaves us with 46.
Grab the next digit (4) from the dividend, add it to 46, then carry on: 464 / 84

Let's proceed to step 6:
The number 84 fits into 464 5 times, leaving a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 9785.0
Subtract 420 from 464 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.

Step 7:
84 goes into 440 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 9785.5
If we take 420 away from 440, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
84 goes into 200 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 9785.52
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
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: 9785.523
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.

Moving on to step 10:
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: 9785.5238
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.

Advancing to step 11:
84 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 9785.5238
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.

Moving on to step 12:
If we divide 800 by 84, we get 9 and a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 9785.523809
Deduct 756 from 800 and we're left 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.

Advancing to step 13:
84 goes into 440 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 9785.5238095
Subtract 420 from 440 to get 20.
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 14:
The number 84 fits into 200 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 9785.52380952
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 9785.52380952 with a remainder of 3.2e-08.
