Let's divide 992181 by 21
We're looking to find how many times 21 goes into 992181.

Advancing to step 1:
When dividing 9 by 21, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 21

Advancing to step 2:
21 can be fit into 99 4 times, resulting in a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 84 from 99, we get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 21

On to step 3:
The number 21 fits into 152 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 147 from 152 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 21

Advancing to step 4:
When dividing 51 by 21, we get 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 472.0
Subtracting 42 from 51 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 21

On to step 5:
21 can be fit into 98 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4724.0
The remainder is 14 after subtracting 84 from 98.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 21

Moving on to step 6:
The number 21 fits into 141 6 times, leaving a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 47246.0
Subtract 126 from 141 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
The number 21 fits into 150 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 47246.7
Deduct 147 from 150 and we're left 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.

Let's proceed to step 8:
30 divided by 21 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 47246.71
If we take 21 away from 30, we end up 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.

Going ahead to step 9:
21 goes into 90 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 47246.714
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.

Let's proceed to step 10:
21 goes into 60 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 47246.7142
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 11:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 47246.71428
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.

Going ahead to step 12:
21 goes into 120 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 47246.714285
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.

Going ahead to step 13:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 47246.7142857
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.

Step 14:
If we divide 30 by 21, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 47246.71428571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 47246.71428571 with a remaining 9e-09.
