807519 ÷ 78 
Let's see how many times 78 fits into 807519.

Advancing to step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 78

Step 2:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 78 from 80 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 78

Advancing to step 3:
When dividing 27 by 78, we get 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 27 leaves us with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 78

Going ahead to step 4:
The number 78 fits into 275 3 times, leaving a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 103.0
If we subtract 234 from 275, we get 41.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 78

Going ahead to step 5:
The number 78 fits into 411 5 times, leaving a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 1035.0
Deduct 390 from 411 and we're left with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 78

Let's proceed to step 6:
78 can be fit into 219 2 times, resulting in a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 10352.0
Subtracting 156 from 219 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
630 divided by 78 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 10352.8
If we subtract 624 from 630, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
78 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 10352.8
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
78 goes into 600 7 times with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 10352.807
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
When dividing 540 by 78, we get 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 10352.8076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
If we divide 720 by 78, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 10352.80769
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
When dividing 180 by 78, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 10352.807692
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
78 can be fit into 240 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 10352.8076923
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
78 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10352.8076923
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 10352.8076923 with a balance of 6e-08.
