992508 ÷ 21 
We want to divide 992508 by 21.

Let's proceed 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
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 21

Moving on to step 2:
21 goes into 99 4 times with a remainder of 15.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 84 from 99, we get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 21

Moving on to step 3:
If we divide 152 by 21, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtract 147 from 152 to get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 21

Let's proceed to step 4:
21 goes into 55 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 472.0
Subtracting 42 from 55 leaves us with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 21

Moving on to step 5:
21 goes into 130 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 4726.0
If we subtract 126 from 130, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 21

Moving on to step 6:
The number 21 fits into 48 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 47262.0
Subtracting 42 from 48 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.

Going ahead to step 7:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 47262.2
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.

Moving on to step 8:
If we divide 180 by 21, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 47262.28
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.

On to step 9:
If we divide 120 by 21, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 47262.285
If we subtract 105 from 120, we 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 10:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 47262.2857
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.

Step 11:
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: 47262.28571
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.

Let's proceed to step 12:
21 goes into 90 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 47262.285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 47262.2857142
Subtracting 42 from 60 leaves us 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.

Going ahead to step 14:
When dividing 180 by 21, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 47262.28571428
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.

Our division results in 47262.28571428 with a remaining 1.2e-08.
