We're dividing 989882 by 21 
We're looking to find how many times 21 goes into 989882.

Step 1:
If we divide 9 by 21, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 21

Advancing to step 2:
98 divided by 21 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
If we take 84 away from 98, we end up with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 21

Advancing to step 3:
21 goes into 149 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 147 away from 149, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 21

Going ahead to step 4:
If we divide 28 by 21, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 471.0
Deduct 21 from 28 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 21

Step 5:
If we divide 78 by 21, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 4713.0
Deduct 63 from 78 and we're left with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 21

On to step 6:
21 goes into 152 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 47137.0
Subtracting 147 from 152 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
21 goes into 50 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 47137.2
If we subtract 42 from 50, we get 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 8:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 47137.23
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
170 divided by 21 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 47137.238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
If we divide 20 by 21, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 47137.238
Subtract 0 from 20 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.

Step 11:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 47137.23809
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
110 divided by 21 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 47137.238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
When dividing 50 by 21, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 47137.2380952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
21 goes into 80 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 47137.23809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 47137.23809523 with a remainder of 1.7e-08.
