20797774 ÷ 869 
We're looking to find how many times 869 goes into 20797774.

Going ahead to step 1:
869 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 869

Advancing to step 2:
869 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 take 0 away from 20, we end up with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 869

Advancing to step 3:
869 can be fit into 207 0 times, resulting in a remainder of 207.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 207, we get 207.
Include the next digit (9) from the dividend after 207, then repeat: 2079 / 869

On to step 4:
When dividing 2079 by 869, we get 2 with a remainder of 341.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1738 from 2079 and we're left with 341.
Include the next digit (7) from the dividend after 341, then repeat: 3417 / 869

On to step 5:
The number 869 fits into 3417 3 times, leaving a remainder of 810.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 2607 from 3417 and we're left with 810.
Append the next digit (7) from the dividend to 810 and continue with: 8107 / 869

Step 6:
869 can be fit into 8107 9 times, resulting in a remainder of 286.
Write down 9 as next digit of the result. 
Result so far: 239.0
Deduct 7821 from 8107 and we're left with 286.
Include the next digit (7) from the dividend after 286, then repeat: 2867 / 869

Advancing to step 7:
The number 869 fits into 2867 3 times, leaving a remainder of 260.
Put 3 as the next digit of the answer. 
Result so far: 2393.0
Deduct 2607 from 2867 and we're left with 260.
Take the next digit (4) from the dividend and append it to 260, then repeat: 2604 / 869

On to step 8:
If we divide 2604 by 869, we get 2 and a remainder of 866.
The next digit of our result is 2. 
Result so far: 23932.0
The remainder is 866 after subtracting 1738 from 2604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8660, and continue the process.

Moving on to step 9:
8660 divided by 869 is 9 with a remainder of 839.
Use 9 as the next digit of our solution. 
Result so far: 23932.9
If we subtract 7821 from 8660, we get 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8390, and continue the process.

Moving on to step 10:
The number 869 fits into 8390 9 times, leaving a remainder of 569.
Record the quotient 9 as the next digit in the result. 
Result so far: 23932.99
Subtracting 7821 from 8390 leaves us with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

The final outcome is 23932.99, with a leftover of 0.569.
