80668524 ÷ 412 
Our goal is to divide 80668524 by 412.

Going ahead to step 1:
When dividing 8 by 412, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 412

Let's proceed to step 2:
412 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 412

On to step 3:
412 can be fit into 806 1 times, resulting in a remainder of 394.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 394 after subtracting 412 from 806.
Append the next digit (6) from the dividend to 394 and continue with: 3946 / 412

Moving on to step 4:
The number 412 fits into 3946 9 times, leaving a remainder of 238.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 3708 from 3946, we get 238.
Append the next digit (8) from the dividend to 238 and continue with: 2388 / 412

Step 5:
412 goes into 2388 5 times with a remainder of 328.
The next digit of our result is 5. 
Result so far: 195.0
Subtract 2060 from 2388 to get 328.
Fetch the next digit (5) from the dividend, attach it to 328 and continue: 3285 / 412

Going ahead to step 6:
When dividing 3285 by 412, we get 7 with a remainder of 401.
Use 7 as the next digit of our solution. 
Result so far: 1957.0
The remainder is 401 after subtracting 2884 from 3285.
Grab the next digit (2) from the dividend, add it to 401, then carry on: 4012 / 412

Step 7:
When dividing 4012 by 412, we get 9 with a remainder of 304.
Record the quotient 9 as the next digit in the result. 
Result so far: 19579.0
If we take 3708 away from 4012, we end up with 304.
Append the next digit (4) from the dividend to 304 and continue with: 3044 / 412

Advancing to step 8:
The number 412 fits into 3044 7 times, leaving a remainder of 160.
Write down 7 as next digit of the result. 
Result so far: 195797.0
Subtracting 2884 from 3044 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 9:
The number 412 fits into 1600 3 times, leaving a remainder of 364.
Put 3 as the next digit of the answer. 
Result so far: 195797.3
Subtracting 1236 from 1600 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 10:
3640 divided by 412 is 8 with a remainder of 344.
Write down 8 as next digit of the result. 
Result so far: 195797.38
The remainder is 344 after subtracting 3296 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 11:
3440 divided by 412 is 8 with a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 195797.388
Subtracting 3296 from 3440 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

In conclusion, the division gives 195797.388 with a balance of 0.0144.
