We look at the division of 20120 by 82 
Let's see how many times 82 fits into 20120.

Step 1:
82 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 82

Let's proceed to step 2:
82 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 82

Let's proceed to step 3:
82 goes into 201 2 times with a remainder of 37.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 37 after subtracting 164 from 201.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 82

Step 4:
If we divide 372 by 82, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 328 from 372 leaves us with 44.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 82

Advancing to step 5:
440 divided by 82 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
The remainder is 30 after subtracting 410 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 6:
82 can be fit into 300 3 times, resulting in a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 245.3
Subtract 246 from 300 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
When dividing 540 by 82, we get 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 245.36
The remainder is 48 after subtracting 492 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
82 goes into 480 5 times with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 245.365
Subtracting 410 from 480 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
82 goes into 700 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 245.3658
If we subtract 656 from 700, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
82 goes into 440 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 245.36585
If we subtract 410 from 440, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
The number 82 fits into 300 3 times, leaving a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 245.365853
If we subtract 246 from 300, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
If we divide 540 by 82, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 245.3658536
If we subtract 492 from 540, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
The number 82 fits into 480 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 245.36585365
Deduct 410 from 480 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 245.36585365 with a balance of 7e-08.
