915644 ÷ 78 
We want to divide 915644 by 78.

Going ahead to step 1:
78 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 78

Going ahead to step 2:
When dividing 91 by 78, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 78 from 91 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 78

On to step 3:
78 can be fit into 135 1 times, resulting in a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 78 from 135 to get 57.
Include the next digit (6) from the dividend after 57, then repeat: 576 / 78

Let's proceed to step 4:
If we divide 576 by 78, we get 7 and a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
The remainder is 30 after subtracting 546 from 576.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 78

Step 5:
78 can be fit into 304 3 times, resulting in a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 1173.0
Deduct 234 from 304 and we're left with 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 78

Let's proceed to step 6:
The number 78 fits into 704 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 11739.0
If we take 702 away from 704, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 78 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11739.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 78 fits into 200 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 11739.02
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
78 goes into 440 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 11739.025
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
78 goes into 500 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 11739.0256
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
78 can be fit into 320 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 11739.02564
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
80 divided by 78 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 11739.025641
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
When dividing 20 by 78, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 11739.025641
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
If we divide 200 by 78, we get 2 and a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 11739.02564102
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 11739.02564102, and the remainder is 4.4e-08.
