13939997 divided by 820 
Let's see how many times 820 fits into 13939997.

Step 1:
820 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 820

Let's proceed to step 2:
820 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 820

Moving on to step 3:
820 can be fit into 139 0 times, resulting in a remainder of 139.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 139 leaves us with 139.
Fetch the next digit (3) from the dividend, attach it to 139 and continue: 1393 / 820

Let's proceed to step 4:
The number 820 fits into 1393 1 times, leaving a remainder of 573.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 820 away from 1393, we end up with 573.
Take the next digit (9) from the dividend and append it to 573, then repeat: 5739 / 820

Let's proceed to step 5:
If we divide 5739 by 820, we get 6 and a remainder of 819.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 4920 from 5739 and we're left with 819.
Fetch the next digit (9) from the dividend, attach it to 819 and continue: 8199 / 820

On to step 6:
8199 divided by 820 is 9 with a remainder of 819.
The next digit of our result is 9. 
Result so far: 169.0
The remainder is 819 after subtracting 7380 from 8199.
Append the next digit (9) from the dividend to 819 and continue with: 8199 / 820

Advancing to step 7:
When dividing 8199 by 820, we get 9 with a remainder of 819.
The next digit of our result is 9. 
Result so far: 1699.0
Deduct 7380 from 8199 and we're left with 819.
Take the next digit (7) from the dividend and append it to 819, then repeat: 8197 / 820

Advancing to step 8:
820 goes into 8197 9 times with a remainder of 817.
The number 9 becomes the next digit in our result. 
Result so far: 16999.0
If we take 7380 away from 8197, we end up with 817.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8170, and continue the process.

Going ahead to step 9:
When dividing 8170 by 820, we get 9 with a remainder of 790.
Use 9 as the next digit of our solution. 
Result so far: 16999.9
Subtract 7380 from 8170 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Advancing to step 10:
The number 820 fits into 7900 9 times, leaving a remainder of 520.
Write down 9 as next digit of the result. 
Result so far: 16999.99
Deduct 7380 from 7900 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final outcome is 16999.99, with a leftover of 0.52.
