We divide 830497 by 78
We're looking to find how many times 78 goes into 830497.

On to step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 78

Going ahead to step 2:
78 goes into 83 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 5 after subtracting 78 from 83.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 78

Going ahead to step 3:
78 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 50 to get 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 78

Step 4:
504 divided by 78 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Deduct 468 from 504 and we're left with 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 78

Going ahead to step 5:
When dividing 369 by 78, we get 4 with a remainder of 57.
The number 4 becomes the next digit in our result. 
Result so far: 1064.0
Deduct 312 from 369 and we're left with 57.
Grab the next digit (7) from the dividend, add it to 57, then carry on: 577 / 78

Step 6:
The number 78 fits into 577 7 times, leaving a remainder of 31.
The next digit of our result is 7. 
Result so far: 10647.0
If we take 546 away from 577, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
If we divide 310 by 78, we get 3 and a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 10647.3
Subtracting 234 from 310 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
78 goes into 760 9 times with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 10647.39
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 10647.397
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
When dividing 340 by 78, we get 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 10647.3974
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
When dividing 280 by 78, we get 3 with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 10647.39743
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
The number 78 fits into 460 5 times, leaving a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 10647.397435
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
78 goes into 700 8 times with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 10647.3974358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 14:
When dividing 760 by 78, we get 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 10647.39743589
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 10647.39743589, and the remainder is 5.8e-08.
