929982 ÷ 21 
We want to figure out the number of times 929982 can be divided by 21.

Advancing to step 1:
21 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 21

Let's proceed to step 2:
21 goes into 92 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 8 after subtracting 84 from 92.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 21

Moving on to step 3:
If we divide 89 by 21, we get 4 and a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 44.0
The remainder is 5 after subtracting 84 from 89.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 21

Let's proceed to step 4:
21 goes into 59 2 times with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 442.0
The remainder is 17 after subtracting 42 from 59.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 21

Going ahead to step 5:
21 can be fit into 178 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 4428.0
If we take 168 away from 178, we end up with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 21

Step 6:
If we divide 102 by 21, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 44284.0
If we take 84 away from 102, we end up 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 7:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 44284.8
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.

Going ahead to step 8:
If we divide 120 by 21, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 44284.85
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.

On to step 9:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 44284.857
Subtract 147 from 150 to get 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 10:
21 goes into 30 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 44284.8571
Deduct 21 from 30 and we're left 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.

Moving on to step 11:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 44284.85714
Deduct 84 from 90 and we're left 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.

Advancing to step 12:
If we divide 60 by 21, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 44284.857142
Deduct 42 from 60 and we're left 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.

Let's proceed to step 13:
When dividing 180 by 21, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 44284.8571428
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.

Step 14:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 44284.85714285
Subtract 105 from 120 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.

The final result is 44284.85714285 with a remainder of 1.5e-08.
