69581309 ÷ 820 
Our goal is to divide 69581309 by 820.

Let's proceed to step 1:
6 divided by 820 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 820

Advancing to step 2:
When dividing 69 by 820, we get 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 820

On to step 3:
When dividing 695 by 820, we get 0 with a remainder of 695.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 695 and we're left with 695.
Append the next digit (8) from the dividend to 695 and continue with: 6958 / 820

On to step 4:
820 goes into 6958 8 times with a remainder of 398.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6560 away from 6958, we end up with 398.
Grab the next digit (1) from the dividend, add it to 398, then carry on: 3981 / 820

Advancing to step 5:
820 can be fit into 3981 4 times, resulting in a remainder of 701.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
The remainder is 701 after subtracting 3280 from 3981.
Grab the next digit (3) from the dividend, add it to 701, then carry on: 7013 / 820

Let's proceed to step 6:
820 goes into 7013 8 times with a remainder of 453.
Record the quotient 8 as the next digit in the result. 
Result so far: 848.0
Deduct 6560 from 7013 and we're left with 453.
Include the next digit (0) from the dividend after 453, then repeat: 4530 / 820

Advancing to step 7:
If we divide 4530 by 820, we get 5 and a remainder of 430.
Write down 5 as next digit of the result. 
Result so far: 8485.0
The remainder is 430 after subtracting 4100 from 4530.
Grab the next digit (9) from the dividend, add it to 430, then carry on: 4309 / 820

Step 8:
820 goes into 4309 5 times with a remainder of 209.
The next digit of our result is 5. 
Result so far: 84855.0
Deduct 4100 from 4309 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 9:
If we divide 2090 by 820, we get 2 and a remainder of 450.
Record the quotient 2 as the next digit in the result. 
Result so far: 84855.2
If we subtract 1640 from 2090, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 10:
When dividing 4500 by 820, we get 5 with a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 84855.25
If we subtract 4100 from 4500, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 11:
820 can be fit into 4000 4 times, resulting in a remainder of 720.
The number 4 becomes the next digit in our result. 
Result so far: 84855.254
The remainder is 720 after subtracting 3280 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 12:
If we divide 7200 by 820, we get 8 and a remainder of 640.
Use 8 as the next digit of our solution. 
Result so far: 84855.2548
Subtract 6560 from 7200 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 13:
If we divide 6400 by 820, we get 7 and a remainder of 660.
Write down 7 as next digit of the result. 
Result so far: 84855.25487
Subtract 5740 from 6400 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 14:
When dividing 6600 by 820, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 84855.254878
If we take 6560 away from 6600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 15:
820 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 84855.254878
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 16:
4000 divided by 820 is 4 with a remainder of 720.
The number 4 becomes the next digit in our result. 
Result so far: 84855.25487804
Subtracting 3280 from 4000 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

In conclusion, the division gives 84855.25487804 with a balance of 7.2e-07.
