21071 ÷ 16 
Let's see how many times 16 fits into 21071.

Advancing to step 1:
2 divided by 16 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 16

On to step 2:
The number 16 fits into 21 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 16 from 21 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 16

Going ahead to step 3:
If we divide 50 by 16, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 2 after subtracting 48 from 50.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 16

Moving on to step 4:
If we divide 27 by 16, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Subtract 16 from 27 to get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 16

Moving on to step 5:
16 can be fit into 111 6 times, resulting in a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 1316.0
Deduct 96 from 111 and we're left 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 6:
If we divide 150 by 16, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 1316.9
If we take 144 away from 150, we end up 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.

Moving on to step 7:
16 can be fit into 60 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 1316.93
If we subtract 48 from 60, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
The number 16 fits into 120 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 1316.937
Subtract 112 from 120 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.

Let's proceed to step 9:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1316.9375
Subtracting 80 from 80 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1316.9375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1316.9375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1316.9375 with a remainder of 0.0.
