995881 ÷ 21 
We're looking to find how many times 21 goes into 995881.

Step 1:
When dividing 9 by 21, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 21

Advancing to step 2:
The number 21 fits into 99 4 times, leaving a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 84 from 99, we get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 21

Moving on to step 3:
21 can be fit into 155 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we subtract 147 from 155, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 21

On to step 4:
When dividing 88 by 21, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
Subtracting 84 from 88 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 21

Moving on to step 5:
When dividing 48 by 21, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 4742.0
Subtract 42 from 48 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 21

Let's proceed to step 6:
21 goes into 61 2 times with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 47422.0
Subtracting 42 from 61 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
The number 21 fits into 190 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 47422.9
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 47422.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 47422.904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
21 goes into 160 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 47422.9047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 11:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 47422.90476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
When dividing 40 by 21, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 47422.904761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 47422.9047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
If we divide 10 by 21, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 47422.9047619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 47422.9047619 with a remaining 1e-08.
