We look at the division of 820492 by 78 
Let's see how many times 78 fits into 820492.

Step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 78

Moving on to step 2:
78 can be fit into 82 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 78 from 82 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 78

Moving on to step 3:
When dividing 40 by 78, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 40 to get 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 78

Advancing to step 4:
78 can be fit into 404 5 times, resulting in a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
The remainder is 14 after subtracting 390 from 404.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 78

On to step 5:
78 goes into 149 1 times with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 1051.0
The remainder is 71 after subtracting 78 from 149.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 78

Advancing to step 6:
If we divide 712 by 78, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 10519.0
The remainder is 10 after subtracting 702 from 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
78 can be fit into 100 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 10519.1
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 10519.12
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
When dividing 640 by 78, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 10519.128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 10519.1282
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
If we divide 40 by 78, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 10519.1282
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10519.128205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
78 goes into 100 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 10519.1282051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
If we divide 220 by 78, we get 2 and a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 10519.12820512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 10519.12820512 with a remaining 6.4e-08.
