We look at the division of 783091 by 78 
Our goal is to divide 783091 by 78.

Moving on to step 1:
78 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 78

Going ahead to step 2:
78 goes into 78 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 78 from 78 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 78

Let's proceed to step 3:
3 divided by 78 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 78

Let's proceed to step 4:
When dividing 30 by 78, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtract 0 from 30 to get 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 78

Advancing to step 5:
78 goes into 309 3 times with a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 1003.0
Deduct 234 from 309 and we're left with 75.
Fetch the next digit (1) from the dividend, attach it to 75 and continue: 751 / 78

Moving on to step 6:
78 can be fit into 751 9 times, resulting in a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 10039.0
Deduct 702 from 751 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
78 goes into 490 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 10039.6
If we subtract 468 from 490, we 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.

Step 8:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 10039.62
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
78 goes into 640 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 10039.628
If we take 624 away from 640, we end up with 16.
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 goes into 160 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 10039.6282
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
78 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10039.6282
If we subtract 0 from 40, we 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.

On to step 12:
The number 78 fits into 400 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10039.628205
If we take 390 away from 400, we end up 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.

On to step 13:
When dividing 100 by 78, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 10039.6282051
Subtracting 78 from 100 leaves us 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.

Going ahead to step 14:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 10039.62820512
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.

The final result is 10039.62820512 with a remainder of 6.4e-08.
