We want to divide 78766349 by 804.

Advancing to step 1:
7 divided by 804 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 804

Moving on to step 2:
The number 804 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 804

Moving on to step 3:
787 divided by 804 is 0 with a remainder of 787.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 787 after subtracting 0 from 787.
Include the next digit (6) from the dividend after 787, then repeat: 7876 / 804

On to step 4:
When dividing 7876 by 804, we get 9 with a remainder of 640.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 7236 from 7876 and we're left with 640.
Bring next digit (6) of the dividend behind the 640 and repeat the process: 6406 / 804

Moving on to step 5:
804 goes into 6406 7 times with a remainder of 778.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Deduct 5628 from 6406 and we're left with 778.
Take the next digit (3) from the dividend and append it to 778, then repeat: 7783 / 804

On to step 6:
If we divide 7783 by 804, we get 9 and a remainder of 547.
Write down 9 as next digit of the result. 
Result so far: 979.0
Deduct 7236 from 7783 and we're left with 547.
Bring next digit (4) of the dividend behind the 547 and repeat the process: 5474 / 804

Advancing to step 7:
If we divide 5474 by 804, we get 6 and a remainder of 650.
The next digit of our result is 6. 
Result so far: 9796.0
The remainder is 650 after subtracting 4824 from 5474.
Include the next digit (9) from the dividend after 650, then repeat: 6509 / 804

Moving on to step 8:
804 can be fit into 6509 8 times, resulting in a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 97968.0
Deduct 6432 from 6509 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
804 goes into 770 0 times with a remainder of 770.
Record the quotient 0 as the next digit in the result. 
Result so far: 97968.0
Subtracting 0 from 770 leaves us with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Advancing to step 10:
804 can be fit into 7700 9 times, resulting in a remainder of 464.
The next digit of our result is 9. 
Result so far: 97968.09
Deduct 7236 from 7700 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 11:
When dividing 4640 by 804, we get 5 with a remainder of 620.
The next digit of our result is 5. 
Result so far: 97968.095
The remainder is 620 after subtracting 4020 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 12:
If we divide 6200 by 804, we get 7 and a remainder of 572.
Put 7 as the next digit of the answer. 
Result so far: 97968.0957
Deduct 5628 from 6200 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 13:
The number 804 fits into 5720 7 times, leaving a remainder of 92.
The number 7 becomes the next digit in our result. 
Result so far: 97968.09577
Subtract 5628 from 5720 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 97968.09577 with a remainder of 9.2e-05.
