We divide 811166 by 78
We want to figure out the number of times 811166 can be divided by 78.

On to step 1:
78 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 78

Moving on to step 2:
81 divided by 78 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 78 from 81 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 78

On to step 3:
78 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 31 to get 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 78

On to step 4:
When dividing 311 by 78, we get 3 with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtracting 234 from 311 leaves us with 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 78

Let's proceed to step 5:
If we divide 776 by 78, we get 9 and a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 1039.0
If we take 702 away from 776, we end up with 74.
Include the next digit (6) from the dividend after 74, then repeat: 746 / 78

Moving on to step 6:
The number 78 fits into 746 9 times, leaving a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 10399.0
Subtracting 702 from 746 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
When dividing 440 by 78, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 10399.5
If we take 390 away from 440, we end up 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.

Going ahead to step 8:
If we divide 500 by 78, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 10399.56
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
If we divide 320 by 78, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 10399.564
Subtracting 312 from 320 leaves us 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 10:
78 goes into 80 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 10399.5641
If we take 78 away from 80, 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.

Advancing to step 11:
78 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10399.5641
Deduct 0 from 20 and we're left 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.

Step 12:
78 goes into 200 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 10399.564102
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.

Let's proceed to step 13:
If we divide 440 by 78, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 10399.5641025
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 14:
78 can be fit into 500 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 10399.56410256
If we take 468 away from 500, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 10399.56410256 with a remaining 3.2e-08.
