We divide 822984 by 21
We want to figure out the number of times 822984 can be divided by 21.

Going ahead to step 1:
When dividing 8 by 21, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 21

On to step 2:
21 can be fit into 82 3 times, resulting in a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 63 from 82, we get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 21

Let's proceed to step 3:
21 goes into 192 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 189 away from 192, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 21

Going ahead to step 4:
The number 21 fits into 39 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 391.0
If we subtract 21 from 39, we get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 21

Let's proceed to step 5:
21 can be fit into 188 8 times, resulting in a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 3918.0
Subtracting 168 from 188 leaves us with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 21

Advancing to step 6:
21 can be fit into 204 9 times, resulting in a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 39189.0
The remainder is 15 after subtracting 189 from 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 39189.7
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 39189.71
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
When dividing 90 by 21, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 39189.714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
If we divide 60 by 21, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 39189.7142
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
If we divide 180 by 21, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 39189.71428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 39189.714285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
150 divided by 21 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 39189.7142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
If we divide 30 by 21, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 39189.71428571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 39189.71428571, and the remainder is 9e-09.
