13385212 ÷ 820 
We're looking to find how many times 820 goes into 13385212.

Step 1:
The number 820 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 820

Moving on to step 2:
When dividing 13 by 820, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 820

Advancing to step 3:
133 divided by 820 is 0 with a remainder of 133.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 133, we get 133.
Fetch the next digit (8) from the dividend, attach it to 133 and continue: 1338 / 820

Advancing to step 4:
820 goes into 1338 1 times with a remainder of 518.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 820 from 1338 and we're left with 518.
Take the next digit (5) from the dividend and append it to 518, then repeat: 5185 / 820

On to step 5:
820 can be fit into 5185 6 times, resulting in a remainder of 265.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 4920 from 5185 leaves us with 265.
Append the next digit (2) from the dividend to 265 and continue with: 2652 / 820

Going ahead to step 6:
The number 820 fits into 2652 3 times, leaving a remainder of 192.
Use 3 as the next digit of our solution. 
Result so far: 163.0
If we take 2460 away from 2652, we end up with 192.
Fetch the next digit (1) from the dividend, attach it to 192 and continue: 1921 / 820

Step 7:
820 goes into 1921 2 times with a remainder of 281.
Use 2 as the next digit of our solution. 
Result so far: 1632.0
The remainder is 281 after subtracting 1640 from 1921.
Include the next digit (2) from the dividend after 281, then repeat: 2812 / 820

Let's proceed to step 8:
If we divide 2812 by 820, we get 3 and a remainder of 352.
The next digit of our result is 3. 
Result so far: 16323.0
Subtract 2460 from 2812 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 9:
3520 divided by 820 is 4 with a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 16323.4
Deduct 3280 from 3520 and we're left 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.

Moving on to step 10:
If we divide 2400 by 820, we get 2 and a remainder of 760.
The number 2 becomes the next digit in our result. 
Result so far: 16323.42
Deduct 1640 from 2400 and we're left 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 11:
820 can be fit into 7600 9 times, resulting in a remainder of 220.
Record the quotient 9 as the next digit in the result. 
Result so far: 16323.429
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.

Step 12:
820 can be fit into 2200 2 times, resulting in a remainder of 560.
Record the quotient 2 as the next digit in the result. 
Result so far: 16323.4292
If we take 1640 away from 2200, 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 13:
5600 divided by 820 is 6 with a remainder of 680.
Put 6 as the next digit of the answer. 
Result so far: 16323.42926
Deduct 4920 from 5600 and we're left 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.

On to step 14:
When dividing 6800 by 820, we get 8 with a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 16323.429268
If we subtract 6560 from 6800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 15:
If we divide 2400 by 820, we get 2 and a remainder of 760.
Record the quotient 2 as the next digit in the result. 
Result so far: 16323.4292682
If we take 1640 away from 2400, we end up 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.

Let's proceed to step 16:
When dividing 7600 by 820, we get 9 with a remainder of 220.
Write down 9 as next digit of the result. 
Result so far: 16323.42926829
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.

In conclusion, the division gives 16323.42926829 with a balance of 2.2e-07.
