We look at the division of 283316 by 21 
Let's see how many times 21 fits into 283316.

Going ahead to step 1:
2 divided by 21 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 21

Let's proceed to step 2:
The number 21 fits into 28 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 21 from 28 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 21

On to step 3:
The number 21 fits into 73 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 63 from 73, we get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 21

Moving on to step 4:
When dividing 103 by 21, we get 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 134.0
If we subtract 84 from 103, we get 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 21

Let's proceed to step 5:
If we divide 191 by 21, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 1349.0
The remainder is 2 after subtracting 189 from 191.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 21

Step 6:
If we divide 26 by 21, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 13491.0
Subtract 21 from 26 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.

Step 7:
50 divided by 21 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 13491.2
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.

Step 8:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 13491.23
Subtract 63 from 80 to get 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 9:
If we divide 170 by 21, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 13491.238
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.

Going ahead to step 10:
When dividing 20 by 21, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 13491.238
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.

Advancing to step 11:
200 divided by 21 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 13491.23809
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.

Going ahead to step 12:
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: 13491.238095
Deduct 105 from 110 and we're left 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.

Advancing to step 13:
21 can be fit into 50 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 13491.2380952
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.

On to step 14:
21 goes into 80 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 13491.23809523
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.

The quotient of the division is 13491.23809523, and the remainder is 1.7e-08.
