We look at the division of 20516323 by 789 
We're looking to find how many times 789 goes into 20516323.

Let's proceed to step 1:
789 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 789

Step 2:
789 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 789

Going ahead to step 3:
When dividing 205 by 789, we get 0 with a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 205 leaves us with 205.
Grab the next digit (1) from the dividend, add it to 205, then carry on: 2051 / 789

On to step 4:
The number 789 fits into 2051 2 times, leaving a remainder of 473.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1578 from 2051 to get 473.
Take the next digit (6) from the dividend and append it to 473, then repeat: 4736 / 789

Let's proceed to step 5:
4736 divided by 789 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 4734 away from 4736, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 789

Moving on to step 6:
789 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 260.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 789

Advancing to step 7:
The number 789 fits into 232 0 times, leaving a remainder of 232.
The number 0 becomes the next digit in our result. 
Result so far: 2600.0
Subtract 0 from 232 to get 232.
Append the next digit (3) from the dividend to 232 and continue with: 2323 / 789

Moving on to step 8:
789 goes into 2323 2 times with a remainder of 745.
The number 2 becomes the next digit in our result. 
Result so far: 26002.0
If we take 1578 away from 2323, we end up with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

On to step 9:
The number 789 fits into 7450 9 times, leaving a remainder of 349.
Write down 9 as next digit of the result. 
Result so far: 26002.9
Deduct 7101 from 7450 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Going ahead to step 10:
The number 789 fits into 3490 4 times, leaving a remainder of 334.
Record the quotient 4 as the next digit in the result. 
Result so far: 26002.94
Deduct 3156 from 3490 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 11:
789 can be fit into 3340 4 times, resulting in a remainder of 184.
The number 4 becomes the next digit in our result. 
Result so far: 26002.944
Subtracting 3156 from 3340 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final outcome is 26002.944, with a leftover of 0.0184.
