We look at the division of 20465392 by 789 
Let's see how many times 789 fits into 20465392.

Moving on to step 1:
The number 789 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 789

Let's proceed to step 2:
The number 789 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 789

Step 3:
789 goes into 204 0 times with a remainder of 204.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 204 after subtracting 0 from 204.
Append the next digit (6) from the dividend to 204 and continue with: 2046 / 789

Advancing to step 4:
The number 789 fits into 2046 2 times, leaving a remainder of 468.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1578 away from 2046, we end up with 468.
Include the next digit (5) from the dividend after 468, then repeat: 4685 / 789

Going ahead to step 5:
The number 789 fits into 4685 5 times, leaving a remainder of 740.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 3945 from 4685 and we're left with 740.
Include the next digit (3) from the dividend after 740, then repeat: 7403 / 789

Advancing to step 6:
7403 divided by 789 is 9 with a remainder of 302.
The number 9 becomes the next digit in our result. 
Result so far: 259.0
If we subtract 7101 from 7403, we get 302.
Take the next digit (9) from the dividend and append it to 302, then repeat: 3029 / 789

Let's proceed to step 7:
3029 divided by 789 is 3 with a remainder of 662.
Write down 3 as next digit of the result. 
Result so far: 2593.0
Subtracting 2367 from 3029 leaves us with 662.
Append the next digit (2) from the dividend to 662 and continue with: 6622 / 789

Let's proceed to step 8:
If we divide 6622 by 789, we get 8 and a remainder of 310.
The number 8 becomes the next digit in our result. 
Result so far: 25938.0
Subtracting 6312 from 6622 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 9:
If we divide 3100 by 789, we get 3 and a remainder of 733.
The next digit of our result is 3. 
Result so far: 25938.3
If we subtract 2367 from 3100, we get 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Let's proceed to step 10:
7330 divided by 789 is 9 with a remainder of 229.
The number 9 becomes the next digit in our result. 
Result so far: 25938.39
Subtracting 7101 from 7330 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Advancing to step 11:
If we divide 2290 by 789, we get 2 and a remainder of 712.
Record the quotient 2 as the next digit in the result. 
Result so far: 25938.392
If we take 1578 away from 2290, we end up with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Moving on to step 12:
If we divide 7120 by 789, we get 9 and a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 25938.3929
Subtract 7101 from 7120 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
190 divided by 789 is 0 with a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 25938.3929
Subtracting 0 from 190 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 14:
789 can be fit into 1900 2 times, resulting in a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 25938.392902
The remainder is 322 after subtracting 1578 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 15:
789 can be fit into 3220 4 times, resulting in a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 25938.3929024
The remainder is 64 after subtracting 3156 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 16:
When dividing 640 by 789, we get 0 with a remainder of 640.
The next digit of our result is 0. 
Result so far: 25938.3929024
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final outcome is 25938.3929024, with a leftover of 6.4e-07.
