80380559 ÷ 274 
We want to divide 80380559 by 274.

Step 1:
274 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 274

Moving on to step 2:
274 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 274

Going ahead to step 3:
274 goes into 803 2 times with a remainder of 255.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 548 away from 803, we end up with 255.
Bring next digit (8) of the dividend behind the 255 and repeat the process: 2558 / 274

Let's proceed to step 4:
2558 divided by 274 is 9 with a remainder of 92.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Deduct 2466 from 2558 and we're left with 92.
Bring next digit (0) of the dividend behind the 92 and repeat the process: 920 / 274

Advancing to step 5:
When dividing 920 by 274, we get 3 with a remainder of 98.
Use 3 as the next digit of our solution. 
Result so far: 293.0
The remainder is 98 after subtracting 822 from 920.
Bring next digit (5) of the dividend behind the 98 and repeat the process: 985 / 274

Step 6:
The number 274 fits into 985 3 times, leaving a remainder of 163.
Write down 3 as next digit of the result. 
Result so far: 2933.0
If we subtract 822 from 985, we get 163.
Bring next digit (5) of the dividend behind the 163 and repeat the process: 1635 / 274

Step 7:
274 can be fit into 1635 5 times, resulting in a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 29335.0
The remainder is 265 after subtracting 1370 from 1635.
Bring next digit (9) of the dividend behind the 265 and repeat the process: 2659 / 274

Let's proceed to step 8:
2659 divided by 274 is 9 with a remainder of 193.
Write down 9 as next digit of the result. 
Result so far: 293359.0
Subtracting 2466 from 2659 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 9:
274 can be fit into 1930 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 293359.7
Subtract 1918 from 1930 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
When dividing 120 by 274, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 293359.7
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
The number 274 fits into 1200 4 times, leaving a remainder of 104.
The next digit of our result is 4. 
Result so far: 293359.704
The remainder is 104 after subtracting 1096 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 12:
When dividing 1040 by 274, we get 3 with a remainder of 218.
Put 3 as the next digit of the answer. 
Result so far: 293359.7043
If we subtract 822 from 1040, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 13:
When dividing 2180 by 274, we get 7 with a remainder of 262.
Use 7 as the next digit of our solution. 
Result so far: 293359.70437
If we take 1918 away from 2180, 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 14:
When dividing 2620 by 274, we get 9 with a remainder of 154.
Write down 9 as next digit of the result. 
Result so far: 293359.704379
Subtract 2466 from 2620 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 15:
When dividing 1540 by 274, we get 5 with a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 293359.7043795
If we take 1370 away from 1540, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 16:
If we divide 1700 by 274, we get 6 and a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 293359.70437956
Deduct 1644 from 1700 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 293359.70437956 with a balance of 5.6e-08.
