We look at the division of 822954 by 21 
We're looking to find how many times 21 goes into 822954.

Step 1:
The number 21 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 21

Moving on to step 2:
82 divided by 21 is 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 63 from 82 to get 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 21

On to step 3:
When dividing 192 by 21, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 189 from 192, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 21

Let's proceed to step 4:
21 can be fit into 39 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 391.0
If we take 21 away from 39, we end up with 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 21

Step 5:
185 divided by 21 is 8 with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 3918.0
Subtracting 168 from 185 leaves us with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 21

Let's proceed to step 6:
21 can be fit into 174 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 39188.0
If we take 168 away from 174, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 21, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 39188.2
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 39188.28
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 21, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 39188.285
If we take 105 away from 120, we end up 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.

Let's proceed to step 10:
When dividing 150 by 21, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 39188.2857
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 39188.28571
If we subtract 21 from 30, we get 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 12:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 39188.285714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
21 can be fit into 60 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 39188.2857142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
180 divided by 21 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 39188.28571428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 39188.28571428 with a remainder of 1.2e-08.
