We're dividing 791866 by 78 
We want to figure out the number of times 791866 can be divided by 78.

Let's proceed to step 1:
If we divide 7 by 78, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 78

Advancing to step 2:
If we divide 79 by 78, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 78 from 79 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 78

On to step 3:
The number 78 fits into 11 0 times, leaving a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 11 leaves us with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 78

Step 4:
78 can be fit into 118 1 times, resulting in a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 101.0
The remainder is 40 after subtracting 78 from 118.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 78

On to step 5:
78 goes into 406 5 times with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 1015.0
The remainder is 16 after subtracting 390 from 406.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 78

Step 6:
The number 78 fits into 166 2 times, leaving a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 10152.0
If we subtract 156 from 166, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
78 goes into 100 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 10152.1
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 10152.12
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
640 divided by 78 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 10152.128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
78 can be fit into 160 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 10152.1282
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10152.1282
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
If we divide 400 by 78, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 10152.128205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
78 can be fit into 100 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 10152.1282051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
220 divided by 78 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 10152.12820512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 10152.12820512 with a balance of 6.4e-08.
