We look at the division of 78209868 by 811 
Let's see how many times 811 fits into 78209868.

Moving on to step 1:
811 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 811

Step 2:
The number 811 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 811

Let's proceed to step 3:
If we divide 782 by 811, we get 0 and a remainder of 782.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 782 and we're left with 782.
Bring next digit (0) of the dividend behind the 782 and repeat the process: 7820 / 811

On to step 4:
7820 divided by 811 is 9 with a remainder of 521.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 7299 from 7820, we get 521.
Fetch the next digit (9) from the dividend, attach it to 521 and continue: 5219 / 811

Moving on to step 5:
If we divide 5219 by 811, we get 6 and a remainder of 353.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 353 after subtracting 4866 from 5219.
Include the next digit (8) from the dividend after 353, then repeat: 3538 / 811

Advancing to step 6:
The number 811 fits into 3538 4 times, leaving a remainder of 294.
The number 4 becomes the next digit in our result. 
Result so far: 964.0
If we subtract 3244 from 3538, we get 294.
Include the next digit (6) from the dividend after 294, then repeat: 2946 / 811

Advancing to step 7:
When dividing 2946 by 811, we get 3 with a remainder of 513.
Put 3 as the next digit of the answer. 
Result so far: 9643.0
Subtracting 2433 from 2946 leaves us with 513.
Fetch the next digit (8) from the dividend, attach it to 513 and continue: 5138 / 811

Moving on to step 8:
The number 811 fits into 5138 6 times, leaving a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 96436.0
Deduct 4866 from 5138 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 9:
2720 divided by 811 is 3 with a remainder of 287.
Record the quotient 3 as the next digit in the result. 
Result so far: 96436.3
If we subtract 2433 from 2720, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Going ahead to step 10:
811 can be fit into 2870 3 times, resulting in a remainder of 437.
Put 3 as the next digit of the answer. 
Result so far: 96436.33
Subtracting 2433 from 2870 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Our division results in 96436.33 with a remaining 0.437.
