81802862 ÷ 412 
Our goal is to divide 81802862 by 412.

Going ahead to step 1:
412 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 412

Going ahead to step 2:
If we divide 81 by 412, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (8) from the dividend after 81, then repeat: 818 / 412

Advancing to step 3:
818 divided by 412 is 1 with a remainder of 406.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 412 from 818 to get 406.
Grab the next digit (0) from the dividend, add it to 406, then carry on: 4060 / 412

On to step 4:
4060 divided by 412 is 9 with a remainder of 352.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 3708 from 4060 and we're left with 352.
Fetch the next digit (2) from the dividend, attach it to 352 and continue: 3522 / 412

On to step 5:
412 goes into 3522 8 times with a remainder of 226.
The next digit of our result is 8. 
Result so far: 198.0
Subtract 3296 from 3522 to get 226.
Append the next digit (8) from the dividend to 226 and continue with: 2268 / 412

Let's proceed to step 6:
When dividing 2268 by 412, we get 5 with a remainder of 208.
The next digit of our result is 5. 
Result so far: 1985.0
Subtracting 2060 from 2268 leaves us with 208.
Append the next digit (6) from the dividend to 208 and continue with: 2086 / 412

Going ahead to step 7:
The number 412 fits into 2086 5 times, leaving a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 19855.0
The remainder is 26 after subtracting 2060 from 2086.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 412

Advancing to step 8:
If we divide 262 by 412, we get 0 and a remainder of 262.
Record the quotient 0 as the next digit in the result. 
Result so far: 198550.0
If we take 0 away from 262, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 9:
The number 412 fits into 2620 6 times, leaving a remainder of 148.
Put 6 as the next digit of the answer. 
Result so far: 198550.6
Subtract 2472 from 2620 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 10:
The number 412 fits into 1480 3 times, leaving a remainder of 244.
Put 3 as the next digit of the answer. 
Result so far: 198550.63
Subtract 1236 from 1480 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 11:
2440 divided by 412 is 5 with a remainder of 380.
The number 5 becomes the next digit in our result. 
Result so far: 198550.635
Subtract 2060 from 2440 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 12:
The number 412 fits into 3800 9 times, leaving a remainder of 92.
Use 9 as the next digit of our solution. 
Result so far: 198550.6359
The remainder is 92 after subtracting 3708 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 13:
The number 412 fits into 920 2 times, leaving a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 198550.63592
If we subtract 824 from 920, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
When dividing 960 by 412, we get 2 with a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 198550.635922
If we take 824 away from 960, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 198550.635922 and a remainder of 1.36e-05.
