We're dividing 82471 by 21 
We're looking to find how many times 21 goes into 82471.

Going ahead to step 1:
21 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 21

Moving on to step 2:
82 divided by 21 is 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 19 after subtracting 63 from 82.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 21

Let's proceed to step 3:
21 can be fit into 194 9 times, resulting in a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 189 from 194, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 21

Step 4:
57 divided by 21 is 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 392.0
Subtracting 42 from 57 leaves us with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 21

Advancing to step 5:
The number 21 fits into 151 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 3927.0
If we subtract 147 from 151, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 6:
If we divide 40 by 21, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 3927.1
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
190 divided by 21 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3927.19
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
21 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3927.19
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
If we divide 100 by 21, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 3927.1904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 3927.19047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
If we divide 130 by 21, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 3927.190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 3927.1904761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 3927.19047619
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 3927.19047619 with a remainder of 1e-09.
