20879777 divided by 809 
Our goal is to divide 20879777 by 809.

On to step 1:
If we divide 2 by 809, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 809

Step 2:
809 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 809

Going ahead to step 3:
When dividing 208 by 809, we get 0 with a remainder of 208.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 208 leaves us with 208.
Take the next digit (7) from the dividend and append it to 208, then repeat: 2087 / 809

Step 4:
When dividing 2087 by 809, we get 2 with a remainder of 469.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1618 from 2087 to get 469.
Append the next digit (9) from the dividend to 469 and continue with: 4699 / 809

Moving on to step 5:
The number 809 fits into 4699 5 times, leaving a remainder of 654.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 4045 from 4699 and we're left with 654.
Append the next digit (7) from the dividend to 654 and continue with: 6547 / 809

Advancing to step 6:
If we divide 6547 by 809, we get 8 and a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 258.0
Deduct 6472 from 6547 and we're left with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 809

Going ahead to step 7:
809 goes into 757 0 times with a remainder of 757.
The next digit of our result is 0. 
Result so far: 2580.0
Subtract 0 from 757 to get 757.
Bring next digit (7) of the dividend behind the 757 and repeat the process: 7577 / 809

Moving on to step 8:
If we divide 7577 by 809, we get 9 and a remainder of 296.
The number 9 becomes the next digit in our result. 
Result so far: 25809.0
Deduct 7281 from 7577 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 9:
809 goes into 2960 3 times with a remainder of 533.
The next digit of our result is 3. 
Result so far: 25809.3
Subtract 2427 from 2960 to get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Advancing to step 10:
5330 divided by 809 is 6 with a remainder of 476.
Record the quotient 6 as the next digit in the result. 
Result so far: 25809.36
If we take 4854 away from 5330, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 11:
4760 divided by 809 is 5 with a remainder of 715.
Put 5 as the next digit of the answer. 
Result so far: 25809.365
If we take 4045 away from 4760, we end up with 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Step 12:
809 goes into 7150 8 times with a remainder of 678.
Use 8 as the next digit of our solution. 
Result so far: 25809.3658
Deduct 6472 from 7150 and we're left with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Step 13:
809 can be fit into 6780 8 times, resulting in a remainder of 308.
Write down 8 as next digit of the result. 
Result so far: 25809.36588
Deduct 6472 from 6780 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

In conclusion, the division gives 25809.36588 with a balance of 0.000308.
