783809 divided by 78 
Our goal is to divide 783809 by 78.

Let's proceed to step 1:
If we divide 7 by 78, we get 0 and 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 / 78

Let's proceed to step 2:
78 can be fit into 78 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 78 from 78.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 78

On to step 3:
When dividing 3 by 78, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 78

Going ahead to step 4:
The number 78 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we subtract 0 from 38, we get 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 78

Let's proceed to step 5:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 1004.0
Subtract 312 from 380 to get 68.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 78

Moving on to step 6:
689 divided by 78 is 8 with a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 10048.0
If we subtract 624 from 689, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
78 goes into 650 8 times with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 10048.8
Subtract 624 from 650 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
78 can be fit into 260 3 times, resulting in a remainder of 26.
The next digit of our result is 3. 
Result so far: 10048.83
Subtract 234 from 260 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
The number 78 fits into 260 3 times, leaving a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 10048.833
If we take 234 away from 260, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 10048.833 with a balance of 0.0026.
