780606 divided by 78 
Our goal is to divide 780606 by 78.

Going ahead to step 1:
78 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 78

Going ahead to step 2:
When dividing 78 by 78, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 78 from 78 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 78

Going ahead to step 3:
When dividing 0 by 78, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 78

Step 4:
6 divided by 78 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 78

Moving on to step 5:
78 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1000.0
The remainder is 60 after subtracting 0 from 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 78

Step 6:
606 divided by 78 is 7 with a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 10007.0
Subtracting 546 from 606 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.

Going ahead to step 7:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 10007.7
Subtracting 546 from 600 leaves us 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.

Step 8:
78 goes into 540 6 times with a remainder of 72.
The next digit of our result is 6. 
Result so far: 10007.76
Subtract 468 from 540 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 10007.769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 10007.7692
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
If we divide 240 by 78, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 10007.76923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
78 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10007.76923
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
When dividing 600 by 78, we get 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 10007.7692307
Deduct 546 from 600 and we're left 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.

Going ahead to step 14:
540 divided by 78 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 10007.76923076
Subtract 468 from 540 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 10007.76923076 and a remainder of 7.2e-08.
