16708497 ÷ 780 
Our goal is to divide 16708497 by 780.

Going ahead to step 1:
780 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 780

Step 2:
16 divided by 780 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 780

Step 3:
If we divide 167 by 780, we get 0 and a remainder of 167.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 167 to get 167.
Include the next digit (0) from the dividend after 167, then repeat: 1670 / 780

Advancing to step 4:
780 can be fit into 1670 2 times, resulting in a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1560 from 1670 and we're left with 110.
Bring next digit (8) of the dividend behind the 110 and repeat the process: 1108 / 780

Let's proceed to step 5:
1108 divided by 780 is 1 with a remainder of 328.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 780 from 1108, we get 328.
Take the next digit (4) from the dividend and append it to 328, then repeat: 3284 / 780

Moving on to step 6:
3284 divided by 780 is 4 with a remainder of 164.
Use 4 as the next digit of our solution. 
Result so far: 214.0
The remainder is 164 after subtracting 3120 from 3284.
Include the next digit (9) from the dividend after 164, then repeat: 1649 / 780

Step 7:
780 goes into 1649 2 times with a remainder of 89.
The number 2 becomes the next digit in our result. 
Result so far: 2142.0
If we take 1560 away from 1649, we end up with 89.
Fetch the next digit (7) from the dividend, attach it to 89 and continue: 897 / 780

On to step 8:
780 goes into 897 1 times with a remainder of 117.
Put 1 as the next digit of the answer. 
Result so far: 21421.0
The remainder is 117 after subtracting 780 from 897.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 9:
When dividing 1170 by 780, we get 1 with a remainder of 390.
Use 1 as the next digit of our solution. 
Result so far: 21421.1
If we take 780 away from 1170, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
780 can be fit into 3900 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 21421.15
Subtract 3900 from 3900 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
When dividing 0 by 780, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21421.15
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
780 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21421.15
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 21421.15 with a balance of 0.0.
