78671810 divided by 412 
We want to figure out the number of times 78671810 can be divided by 412.

On to step 1:
412 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 412

Moving on to step 2:
When dividing 78 by 412, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 412

Going ahead to step 3:
When dividing 786 by 412, we get 1 with a remainder of 374.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 412 from 786 leaves us with 374.
Fetch the next digit (7) from the dividend, attach it to 374 and continue: 3747 / 412

Moving on to step 4:
The number 412 fits into 3747 9 times, leaving a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 3708 from 3747, we get 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 412

Let's proceed to step 5:
391 divided by 412 is 0 with a remainder of 391.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
If we take 0 away from 391, we end up with 391.
Grab the next digit (8) from the dividend, add it to 391, then carry on: 3918 / 412

Moving on to step 6:
3918 divided by 412 is 9 with a remainder of 210.
Record the quotient 9 as the next digit in the result. 
Result so far: 1909.0
The remainder is 210 after subtracting 3708 from 3918.
Take the next digit (1) from the dividend and append it to 210, then repeat: 2101 / 412

Step 7:
If we divide 2101 by 412, we get 5 and a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 19095.0
Subtract 2060 from 2101 to get 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 412

Moving on to step 8:
If we divide 410 by 412, we get 0 and a remainder of 410.
Put 0 as the next digit of the answer. 
Result so far: 190950.0
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 9:
If we divide 4100 by 412, we get 9 and a remainder of 392.
Use 9 as the next digit of our solution. 
Result so far: 190950.9
The remainder is 392 after subtracting 3708 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 10:
If we divide 3920 by 412, we get 9 and a remainder of 212.
The number 9 becomes the next digit in our result. 
Result so far: 190950.99
If we take 3708 away from 3920, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final result is 190950.99 with a remainder of 0.212.
