20404807 ÷ 789 
Our goal is to divide 20404807 by 789.

Let's proceed to step 1:
2 divided by 789 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 789

Moving on to step 2:
789 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 789

Step 3:
204 divided by 789 is 0 with a remainder of 204.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 204 leaves us with 204.
Bring next digit (0) of the dividend behind the 204 and repeat the process: 2040 / 789

Advancing to step 4:
789 can be fit into 2040 2 times, resulting in a remainder of 462.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1578 from 2040, we get 462.
Grab the next digit (4) from the dividend, add it to 462, then carry on: 4624 / 789

Moving on to step 5:
When dividing 4624 by 789, we get 5 with a remainder of 679.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 3945 from 4624, we get 679.
Grab the next digit (8) from the dividend, add it to 679, then carry on: 6798 / 789

Step 6:
When dividing 6798 by 789, we get 8 with a remainder of 486.
Record the quotient 8 as the next digit in the result. 
Result so far: 258.0
If we subtract 6312 from 6798, we get 486.
Grab the next digit (0) from the dividend, add it to 486, then carry on: 4860 / 789

Let's proceed to step 7:
When dividing 4860 by 789, we get 6 with a remainder of 126.
Record the quotient 6 as the next digit in the result. 
Result so far: 2586.0
Deduct 4734 from 4860 and we're left with 126.
Fetch the next digit (7) from the dividend, attach it to 126 and continue: 1267 / 789

Let's proceed to step 8:
789 goes into 1267 1 times with a remainder of 478.
The number 1 becomes the next digit in our result. 
Result so far: 25861.0
Deduct 789 from 1267 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 9:
4780 divided by 789 is 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 25861.6
Subtracting 4734 from 4780 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
789 goes into 460 0 times with a remainder of 460.
The next digit of our result is 0. 
Result so far: 25861.6
The remainder is 460 after subtracting 0 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 11:
4600 divided by 789 is 5 with a remainder of 655.
The next digit of our result is 5. 
Result so far: 25861.605
The remainder is 655 after subtracting 3945 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Moving on to step 12:
789 can be fit into 6550 8 times, resulting in a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 25861.6058
Subtract 6312 from 6550 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 13:
789 can be fit into 2380 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 25861.60583
The remainder is 13 after subtracting 2367 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
130 divided by 789 is 0 with a remainder of 130.
The next digit of our result is 0. 
Result so far: 25861.60583
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 15:
If we divide 1300 by 789, we get 1 and a remainder of 511.
Use 1 as the next digit of our solution. 
Result so far: 25861.6058301
Subtract 789 from 1300 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

On to step 16:
If we divide 5110 by 789, we get 6 and a remainder of 376.
Write down 6 as next digit of the result. 
Result so far: 25861.60583016
Subtracting 4734 from 5110 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final result is 25861.60583016 with a remainder of 3.76e-07.
