20395887 ÷ 791 
We want to divide 20395887 by 791.

Moving on to step 1:
2 divided by 791 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 791

Going ahead to step 2:
791 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 791

Advancing to step 3:
When dividing 203 by 791, we get 0 with a remainder of 203.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 203, we end up with 203.
Bring next digit (9) of the dividend behind the 203 and repeat the process: 2039 / 791

On to step 4:
The number 791 fits into 2039 2 times, leaving a remainder of 457.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1582 from 2039 to get 457.
Bring next digit (5) of the dividend behind the 457 and repeat the process: 4575 / 791

Let's proceed to step 5:
When dividing 4575 by 791, we get 5 with a remainder of 620.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 3955 from 4575 leaves us with 620.
Take the next digit (8) from the dividend and append it to 620, then repeat: 6208 / 791

Moving on to step 6:
If we divide 6208 by 791, we get 7 and a remainder of 671.
The number 7 becomes the next digit in our result. 
Result so far: 257.0
Subtracting 5537 from 6208 leaves us with 671.
Include the next digit (8) from the dividend after 671, then repeat: 6718 / 791

Advancing to step 7:
When dividing 6718 by 791, we get 8 with a remainder of 390.
Write down 8 as next digit of the result. 
Result so far: 2578.0
If we subtract 6328 from 6718, we get 390.
Fetch the next digit (7) from the dividend, attach it to 390 and continue: 3907 / 791

Moving on to step 8:
3907 divided by 791 is 4 with a remainder of 743.
Record the quotient 4 as the next digit in the result. 
Result so far: 25784.0
Deduct 3164 from 3907 and we're left with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Let's proceed to step 9:
7430 divided by 791 is 9 with a remainder of 311.
The next digit of our result is 9. 
Result so far: 25784.9
Subtract 7119 from 7430 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Moving on to step 10:
791 goes into 3110 3 times with a remainder of 737.
Put 3 as the next digit of the answer. 
Result so far: 25784.93
If we take 2373 away from 3110, we end up with 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Let's proceed to step 11:
791 goes into 7370 9 times with a remainder of 251.
Put 9 as the next digit of the answer. 
Result so far: 25784.939
The remainder is 251 after subtracting 7119 from 7370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 12:
The number 791 fits into 2510 3 times, leaving a remainder of 137.
The next digit of our result is 3. 
Result so far: 25784.9393
Subtract 2373 from 2510 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 13:
If we divide 1370 by 791, we get 1 and a remainder of 579.
Record the quotient 1 as the next digit in the result. 
Result so far: 25784.93931
Subtract 791 from 1370 to get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Advancing to step 14:
If we divide 5790 by 791, we get 7 and a remainder of 253.
Put 7 as the next digit of the answer. 
Result so far: 25784.939317
Deduct 5537 from 5790 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 15:
2530 divided by 791 is 3 with a remainder of 157.
The number 3 becomes the next digit in our result. 
Result so far: 25784.9393173
Subtract 2373 from 2530 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 16:
791 goes into 1570 1 times with a remainder of 779.
The next digit of our result is 1. 
Result so far: 25784.93931731
Subtract 791 from 1570 to get 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

In conclusion, the division gives 25784.93931731 with a balance of 7.79e-07.
