We divide 496292 by 21
We're looking to find how many times 21 goes into 496292.

On to step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 21

Going ahead to step 2:
If we divide 49 by 21, we get 2 and a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 7 after subtracting 42 from 49.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 21

Let's proceed to step 3:
21 can be fit into 76 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 63 away from 76, we end up with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 21

Moving on to step 4:
21 can be fit into 132 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 236.0
If we subtract 126 from 132, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 21

Going ahead to step 5:
21 can be fit into 69 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 2363.0
Subtracting 63 from 69 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 21

Step 6:
The number 21 fits into 62 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 23632.0
The remainder is 20 after subtracting 42 from 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
If we divide 200 by 21, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 23632.9
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
21 can be fit into 110 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 23632.95
Subtracting 105 from 110 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.

Step 9:
If we divide 50 by 21, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 23632.952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
80 divided by 21 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 23632.9523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 23632.95238
If we take 168 away from 170, we end up 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.

On to step 12:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 23632.95238
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 23632.9523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 23632.95238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 23632.95238095 and a remainder of 5e-09.
