The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6560 from 6968, we get 408.
Include the next digit (8) from the dividend after 408, then repeat: 4088 / 820

Moving on to step 5:
If we divide 4088 by 820, we get 4 and a remainder of 808.
Put 4 as the next digit of the answer. 
Result so far: 84.0
If we subtract 3280 from 4088, we get 808.
Grab the next digit (0) from the dividend, add it to 808, then carry on: 8080 / 820

On to step 6:
The number 820 fits into 8080 9 times, leaving a remainder of 700.
Record the quotient 9 as the next digit in the result. 
Result so far: 849.0
Subtracting 7380 from 8080 leaves us with 700.
Grab the next digit (0) from the dividend, add it to 700, then carry on: 7000 / 820

Going ahead to step 7:
When dividing 7000 by 820, we get 8 with a remainder of 440.
The number 8 becomes the next digit in our result. 
Result so far: 8498.0
Subtracting 6560 from 7000 leaves us with 440.
Include the next digit (9) from the dividend after 440, then repeat: 4409 / 820

Step 8:
820 goes into 4409 5 times with a remainder of 309.
Use 5 as the next digit of our solution. 
Result so far: 84985.0
Deduct 4100 from 4409 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 9:
820 goes into 3090 3 times with a remainder of 630.
The number 3 becomes the next digit in our result. 
Result so far: 84985.3
Subtract 2460 from 3090 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 10:
The number 820 fits into 6300 7 times, leaving a remainder of 560.
The number 7 becomes the next digit in our result. 
Result so far: 84985.37
If we take 5740 away from 6300, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 11:
When dividing 5600 by 820, we get 6 with a remainder of 680.
The next digit of our result is 6. 
Result so far: 84985.376
Subtracting 4920 from 5600 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 12:
The number 820 fits into 6800 8 times, leaving a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 84985.3768
If we take 6560 away from 6800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 13:
When dividing 2400 by 820, we get 2 with a remainder of 760.
The next digit of our result is 2. 
Result so far: 84985.37682
Subtracting 1640 from 2400 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 14:
When dividing 7600 by 820, we get 9 with a remainder of 220.
Use 9 as the next digit of our solution. 
Result so far: 84985.376829
Deduct 7380 from 7600 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 15:
If we divide 2200 by 820, we get 2 and a remainder of 560.
The number 2 becomes the next digit in our result. 
Result so far: 84985.3768292
The remainder is 560 after subtracting 1640 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 16:
The number 820 fits into 5600 6 times, leaving a remainder of 680.
The next digit of our result is 6. 
Result so far: 84985.37682926
If we take 4920 away from 5600, we end up with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

The final outcome is 84985.37682926, with a leftover of 6.8e-07.
