We're dividing 282801 by 21 
We want to divide 282801 by 21.

Step 1:
21 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 21

Going ahead to step 2:
21 can be fit into 28 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 21 from 28, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 21

Advancing to step 3:
72 divided by 21 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 63 from 72, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 21

Going ahead to step 4:
The number 21 fits into 98 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Subtracting 84 from 98 leaves us with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 21

On to step 5:
140 divided by 21 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 1346.0
Deduct 126 from 140 and we're left with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 21

Let's proceed to step 6:
141 divided by 21 is 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 13466.0
Subtract 126 from 141 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.

Step 7:
150 divided by 21 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 13466.7
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.

Step 8:
When dividing 30 by 21, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 13466.71
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.

Advancing to step 9:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 13466.714
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.

Let's proceed to step 10:
21 goes into 60 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 13466.7142
If we take 42 away from 60, 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.

Step 11:
21 goes into 180 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 13466.71428
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 12:
21 goes into 120 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 13466.714285
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.

Going ahead to step 13:
If we divide 150 by 21, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 13466.7142857
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.

Let's proceed to step 14:
The number 21 fits into 30 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 13466.71428571
Subtracting 21 from 30 leaves us 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.

The final outcome is 13466.71428571, with a leftover of 9e-09.
