816609 ÷ 78 
We're looking to find how many times 78 goes into 816609.

Going ahead to step 1:
8 divided by 78 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 78

Advancing to step 2:
When dividing 81 by 78, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 3 after subtracting 78 from 81.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 78

Advancing to step 3:
78 can be fit into 36 0 times, resulting in a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 36 and we're left with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 78

Step 4:
The number 78 fits into 366 4 times, leaving a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtract 312 from 366 to get 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 78

Advancing to step 5:
If we divide 540 by 78, we get 6 and a remainder of 72.
The next digit of our result is 6. 
Result so far: 1046.0
If we subtract 468 from 540, we get 72.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 78

Step 6:
729 divided by 78 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 10469.0
Subtracting 702 from 729 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
If we divide 270 by 78, we get 3 and a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 10469.3
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 10469.34
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
The number 78 fits into 480 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 10469.346
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 10469.3461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
When dividing 420 by 78, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 10469.34615
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 10469.346153
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 13:
78 goes into 660 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 10469.3461538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
The number 78 fits into 360 4 times, leaving a remainder of 48.
The next digit of our result is 4. 
Result so far: 10469.34615384
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 10469.34615384 with a balance of 4.8e-08.
