We divide 482864 by 21
We want to figure out the number of times 482864 can be divided by 21.

Advancing to step 1:
When dividing 4 by 21, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 21

On to step 2:
21 goes into 48 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 42 from 48 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 21

Moving on to step 3:
62 divided by 21 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 42 from 62 to get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 21

Moving on to step 4:
The number 21 fits into 208 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 229.0
Subtracting 189 from 208 leaves us with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 21

Going ahead to step 5:
The number 21 fits into 196 9 times, leaving a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 2299.0
The remainder is 7 after subtracting 189 from 196.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 21

Moving on to step 6:
74 divided by 21 is 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 22993.0
If we subtract 63 from 74, 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.

Moving on to step 7:
21 goes into 110 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 22993.5
If we take 105 away from 110, we end up 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 8:
If we divide 50 by 21, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 22993.52
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 22993.523
Deduct 63 from 80 and we're left 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.

Going ahead to step 10:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 22993.5238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
21 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 22993.5238
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.

Moving on to step 12:
If we divide 200 by 21, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 22993.523809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 22993.5238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
50 divided by 21 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 22993.52380952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 22993.52380952 and a remainder of 8e-09.
