13288213 ÷ 820 
We want to figure out the number of times 13288213 can be divided by 820.

Going ahead to step 1:
820 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 820

On to step 2:
When dividing 13 by 820, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 820

Step 3:
If we divide 132 by 820, we get 0 and a remainder of 132.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 132, we end up with 132.
Include the next digit (8) from the dividend after 132, then repeat: 1328 / 820

Step 4:
If we divide 1328 by 820, we get 1 and a remainder of 508.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 820 away from 1328, we end up with 508.
Grab the next digit (8) from the dividend, add it to 508, then carry on: 5088 / 820

Going ahead to step 5:
820 can be fit into 5088 6 times, resulting in a remainder of 168.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 4920 from 5088 to get 168.
Take the next digit (2) from the dividend and append it to 168, then repeat: 1682 / 820

Going ahead to step 6:
1682 divided by 820 is 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 162.0
Subtracting 1640 from 1682 leaves us with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 820

On to step 7:
When dividing 421 by 820, we get 0 with a remainder of 421.
Put 0 as the next digit of the answer. 
Result so far: 1620.0
Subtract 0 from 421 to get 421.
Fetch the next digit (3) from the dividend, attach it to 421 and continue: 4213 / 820

Let's proceed to step 8:
4213 divided by 820 is 5 with a remainder of 113.
The next digit of our result is 5. 
Result so far: 16205.0
If we take 4100 away from 4213, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 9:
820 can be fit into 1130 1 times, resulting in a remainder of 310.
The number 1 becomes the next digit in our result. 
Result so far: 16205.1
Subtracting 820 from 1130 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
820 can be fit into 3100 3 times, resulting in a remainder of 640.
Record the quotient 3 as the next digit in the result. 
Result so far: 16205.13
Deduct 2460 from 3100 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 11:
6400 divided by 820 is 7 with a remainder of 660.
Put 7 as the next digit of the answer. 
Result so far: 16205.137
If we take 5740 away from 6400, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 12:
820 can be fit into 6600 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 16205.1378
Subtracting 6560 from 6600 leaves us 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.

On to step 13:
400 divided by 820 is 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 16205.1378
Subtracting 0 from 400 leaves us with 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 14:
The number 820 fits into 4000 4 times, leaving a remainder of 720.
Record the quotient 4 as the next digit in the result. 
Result so far: 16205.137804
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.

Step 15:
If we divide 7200 by 820, we get 8 and a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 16205.1378048
If we take 6560 away from 7200, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 16:
820 goes into 6400 7 times with a remainder of 660.
The next digit of our result is 7. 
Result so far: 16205.13780487
If we subtract 5740 from 6400, we 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.

In conclusion, the division gives 16205.13780487 with a balance of 6.6e-07.
