We're dividing 891366 by 78 
We want to divide 891366 by 78.

Going ahead to step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 78

On to step 2:
78 can be fit into 89 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 78 from 89 to get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 78

Moving on to step 3:
78 goes into 111 1 times with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 78 from 111 and we're left with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 78

Let's proceed to step 4:
333 divided by 78 is 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
The remainder is 21 after subtracting 312 from 333.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 78

Moving on to step 5:
78 goes into 216 2 times with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 1142.0
Deduct 156 from 216 and we're left with 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 78

Step 6:
78 goes into 606 7 times with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 11427.0
Deduct 546 from 606 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
If we divide 600 by 78, we get 7 and a remainder of 54.
The next digit of our result is 7. 
Result so far: 11427.7
If we take 546 away from 600, we end up 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.

On to step 8:
78 goes into 540 6 times with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 11427.76
Subtracting 468 from 540 leaves us with 72.
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 9:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 11427.769
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
180 divided by 78 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 11427.7692
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
If we divide 240 by 78, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 11427.76923
If we take 234 away from 240, we end up 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 12:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 11427.76923
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
78 can be fit into 600 7 times, resulting in a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 11427.7692307
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 14:
78 goes into 540 6 times with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 11427.76923076
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 11427.76923076 with a remainder of 7.2e-08.
