We look at the division of 85516619 by 820 
Our goal is to divide 85516619 by 820.

Moving on to step 1:
If we divide 8 by 820, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 820

Going ahead to step 2:
820 goes into 85 0 times with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Append the next digit (5) from the dividend to 85 and continue with: 855 / 820

Step 3:
855 divided by 820 is 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 820 from 855 and we're left with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 820

Step 4:
If we divide 351 by 820, we get 0 and a remainder of 351.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 351 and we're left with 351.
Fetch the next digit (6) from the dividend, attach it to 351 and continue: 3516 / 820

Step 5:
The number 820 fits into 3516 4 times, leaving a remainder of 236.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Subtract 3280 from 3516 to get 236.
Bring next digit (6) of the dividend behind the 236 and repeat the process: 2366 / 820

Going ahead to step 6:
When dividing 2366 by 820, we get 2 with a remainder of 726.
Put 2 as the next digit of the answer. 
Result so far: 1042.0
If we take 1640 away from 2366, we end up with 726.
Bring next digit (1) of the dividend behind the 726 and repeat the process: 7261 / 820

Let's proceed to step 7:
820 goes into 7261 8 times with a remainder of 701.
The next digit of our result is 8. 
Result so far: 10428.0
Subtracting 6560 from 7261 leaves us with 701.
Fetch the next digit (9) from the dividend, attach it to 701 and continue: 7019 / 820

Let's proceed to step 8:
The number 820 fits into 7019 8 times, leaving a remainder of 459.
Write down 8 as next digit of the result. 
Result so far: 104288.0
The remainder is 459 after subtracting 6560 from 7019.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Moving on to step 9:
When dividing 4590 by 820, we get 5 with a remainder of 490.
Use 5 as the next digit of our solution. 
Result so far: 104288.5
Subtract 4100 from 4590 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 10:
820 can be fit into 4900 5 times, resulting in a remainder of 800.
The next digit of our result is 5. 
Result so far: 104288.55
If we take 4100 away from 4900, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The quotient of the division is 104288.55, and the remainder is 0.8.
