820 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 820

Moving on to step 2:
820 can be fit into 79 0 times, resulting in a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 820

Going ahead to step 3:
798 divided by 820 is 0 with a remainder of 798.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 798 after subtracting 0 from 798.

Let's proceed to step 4:
820 can be fit into 7986 9 times, resulting in a remainder of 606.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 7380 from 7986 and we're left with 606.
Include the next digit (0) from the dividend after 606, then repeat: 6060 / 820

Let's proceed to step 5:
The number 820 fits into 6060 7 times, leaving a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we subtract 5740 from 6060, we get 320.
Include the next digit (5) from the dividend after 320, then repeat: 3205 / 820

Moving on to step 6:
3205 divided by 820 is 3 with a remainder of 745.
Write down 3 as next digit of the result. 
Result so far: 973.0
Subtracting 2460 from 3205 leaves us with 745.
Fetch the next digit (1) from the dividend, attach it to 745 and continue: 7451 / 820

Let's proceed to step 7:
When dividing 7451 by 820, we get 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 9739.0
The remainder is 71 after subtracting 7380 from 7451.
Append the next digit (4) from the dividend to 71 and continue with: 714 / 820

On to step 8:
If we divide 714 by 820, we get 0 and a remainder of 714.
Put 0 as the next digit of the answer. 
Result so far: 97390.0
Subtracting 0 from 714 leaves us with 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Advancing to step 9:
If we divide 7140 by 820, we get 8 and a remainder of 580.
Put 8 as the next digit of the answer. 
Result so far: 97390.8
Subtract 6560 from 7140 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 10:
5800 divided by 820 is 7 with a remainder of 60.
The next digit of our result is 7. 
Result so far: 97390.87
Deduct 5740 from 5800 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
600 divided by 820 is 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 97390.87
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 12:
6000 divided by 820 is 7 with a remainder of 260.
Put 7 as the next digit of the answer. 
Result so far: 97390.8707
If we subtract 5740 from 6000, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 13:
When dividing 2600 by 820, we get 3 with a remainder of 140.
Record the quotient 3 as the next digit in the result. 
Result so far: 97390.87073
If we take 2460 away from 2600, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 14:
The number 820 fits into 1400 1 times, leaving a remainder of 580.
Write down 1 as next digit of the result. 
Result so far: 97390.870731
Deduct 820 from 1400 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 15:
If we divide 5800 by 820, we get 7 and a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 97390.8707317
The remainder is 60 after subtracting 5740 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 16:
If we divide 600 by 820, we get 0 and a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 97390.8707317
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Our division results in 97390.8707317 with a remaining 6e-07.
