We look at the division of 16268993 by 780 
We want to figure out the number of times 16268993 can be divided by 780.

Advancing to step 1:
If we divide 1 by 780, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 780

Moving on to step 2:
780 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 780

On to step 3:
When dividing 162 by 780, we get 0 with a remainder of 162.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 162 leaves us with 162.
Grab the next digit (6) from the dividend, add it to 162, then carry on: 1626 / 780

Let's proceed to step 4:
The number 780 fits into 1626 2 times, leaving a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 66 after subtracting 1560 from 1626.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 780

Moving on to step 5:
If we divide 668 by 780, we get 0 and a remainder of 668.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 668 leaves us with 668.
Include the next digit (9) from the dividend after 668, then repeat: 6689 / 780

Let's proceed to step 6:
6689 divided by 780 is 8 with a remainder of 449.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
Subtract 6240 from 6689 to get 449.
Append the next digit (9) from the dividend to 449 and continue with: 4499 / 780

Going ahead to step 7:
If we divide 4499 by 780, we get 5 and a remainder of 599.
Put 5 as the next digit of the answer. 
Result so far: 2085.0
If we take 3900 away from 4499, we end up with 599.
Take the next digit (3) from the dividend and append it to 599, then repeat: 5993 / 780

Step 8:
The number 780 fits into 5993 7 times, leaving a remainder of 533.
Write down 7 as next digit of the result. 
Result so far: 20857.0
Subtracting 5460 from 5993 leaves us with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Let's proceed to step 9:
When dividing 5330 by 780, we get 6 with a remainder of 650.
The number 6 becomes the next digit in our result. 
Result so far: 20857.6
Subtracting 4680 from 5330 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 10:
780 can be fit into 6500 8 times, resulting in a remainder of 260.
Put 8 as the next digit of the answer. 
Result so far: 20857.68
If we take 6240 away from 6500, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 11:
The number 780 fits into 2600 3 times, leaving a remainder of 260.
Use 3 as the next digit of our solution. 
Result so far: 20857.683
Subtracting 2340 from 2600 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 12:
780 can be fit into 2600 3 times, resulting in a remainder of 260.
The number 3 becomes the next digit in our result. 
Result so far: 20857.6833
If we take 2340 away from 2600, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 20857.6833, with a leftover of 0.0026.
