We look at the division of 20802 by 78 
We're looking to find how many times 78 goes into 20802.

Let's proceed to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 78

Going ahead to step 2:
If we divide 20 by 78, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 78

Let's proceed to step 3:
78 goes into 208 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 52 after subtracting 156 from 208.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 78

Advancing to step 4:
520 divided by 78 is 6 with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 468 away from 520, we end up with 52.
Grab the next digit (2) from the dividend, add it to 52, then carry on: 522 / 78

Step 5:
When dividing 522 by 78, we get 6 with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 266.0
If we subtract 468 from 522, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 6:
If we divide 540 by 78, we get 6 and a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 266.6
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 7:
If we divide 720 by 78, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 266.69
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
When dividing 180 by 78, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 266.692
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
240 divided by 78 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 266.6923
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
If we divide 60 by 78, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 266.6923
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
If we divide 600 by 78, we get 7 and a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 266.692307
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
540 divided by 78 is 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 266.6923076
If we take 468 away from 540, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
78 goes into 720 9 times with a remainder of 18.
The next digit of our result is 9. 
Result so far: 266.69230769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 266.69230769 with a remaining 1.8e-08.
