916840 ÷ 78 
Our goal is to divide 916840 by 78.

Going ahead to step 1:
When dividing 9 by 78, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 78

Let's proceed to step 2:
91 divided by 78 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 78 from 91, we get 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 78

Going ahead to step 3:
The number 78 fits into 136 1 times, leaving a remainder of 58.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 78 from 136 to get 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 78

Going ahead to step 4:
When dividing 588 by 78, we get 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 117.0
The remainder is 42 after subtracting 546 from 588.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 78

Step 5:
78 can be fit into 424 5 times, resulting in a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 1175.0
Subtracting 390 from 424 leaves us with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 78

Going ahead to step 6:
The number 78 fits into 340 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 11754.0
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
280 divided by 78 is 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 11754.3
Subtracting 234 from 280 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
78 can be fit into 460 5 times, resulting in a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 11754.35
Deduct 390 from 460 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
700 divided by 78 is 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 11754.358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
The number 78 fits into 760 9 times, leaving a remainder of 58.
The next digit of our result is 9. 
Result so far: 11754.3589
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 11:
The number 78 fits into 580 7 times, leaving a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 11754.35897
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
If we divide 340 by 78, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 11754.358974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
78 can be fit into 280 3 times, resulting in a remainder of 46.
The next digit of our result is 3. 
Result so far: 11754.3589743
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 14:
If we divide 460 by 78, we get 5 and a remainder of 70.
The next digit of our result is 5. 
Result so far: 11754.35897435
Deduct 390 from 460 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 11754.35897435, and the remainder is 7e-08.
