We divide 662868 by 21
Let's see how many times 21 fits into 662868.

Advancing to step 1:
When dividing 6 by 21, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 21

Let's proceed to step 2:
21 goes into 66 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 3 after subtracting 63 from 66.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 21

Going ahead to step 3:
21 can be fit into 32 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 21 from 32 and we're left with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 21

Going ahead to step 4:
When dividing 118 by 21, we get 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 315.0
Subtracting 105 from 118 leaves us with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 21

On to step 5:
136 divided by 21 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 3156.0
Deduct 126 from 136 and we're left with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 21

Moving on to step 6:
21 can be fit into 108 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 31565.0
Subtract 105 from 108 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.

On to step 7:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 31565.1
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 8:
21 goes into 90 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 31565.14
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.

Advancing to step 9:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 31565.142
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.

Moving on to step 10:
The number 21 fits into 180 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 31565.1428
If we take 168 away from 180, we end up with 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 11:
When dividing 120 by 21, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 31565.14285
Subtracting 105 from 120 leaves us 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 12:
If we divide 150 by 21, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 31565.142857
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 13:
30 divided by 21 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 31565.1428571
If we subtract 21 from 30, we get 9.
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 14:
90 divided by 21 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 31565.14285714
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.

The quotient of the division is 31565.14285714, and the remainder is 6e-09.
