80102564 ÷ 274 
We want to divide 80102564 by 274.

Let's proceed to step 1:
The number 274 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 274

Let's proceed to step 2:
274 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 274

On to step 3:
If we divide 801 by 274, we get 2 and a remainder of 253.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 253 after subtracting 548 from 801.
Append the next digit (0) from the dividend to 253 and continue with: 2530 / 274

Going ahead to step 4:
If we divide 2530 by 274, we get 9 and a remainder of 64.
The next digit of our result is 9. 
Result so far: 29.0
If we take 2466 away from 2530, we end up with 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 274

Step 5:
The number 274 fits into 642 2 times, leaving a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 292.0
If we subtract 548 from 642, we get 94.
Fetch the next digit (5) from the dividend, attach it to 94 and continue: 945 / 274

Advancing to step 6:
945 divided by 274 is 3 with a remainder of 123.
The number 3 becomes the next digit in our result. 
Result so far: 2923.0
The remainder is 123 after subtracting 822 from 945.
Take the next digit (6) from the dividend and append it to 123, then repeat: 1236 / 274

Let's proceed to step 7:
If we divide 1236 by 274, we get 4 and a remainder of 140.
Record the quotient 4 as the next digit in the result. 
Result so far: 29234.0
Subtract 1096 from 1236 to get 140.
Include the next digit (4) from the dividend after 140, then repeat: 1404 / 274

Step 8:
If we divide 1404 by 274, we get 5 and a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 292345.0
Subtracting 1370 from 1404 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
When dividing 340 by 274, we get 1 with a remainder of 66.
The next digit of our result is 1. 
Result so far: 292345.1
Subtracting 274 from 340 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
274 can be fit into 660 2 times, resulting in a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 292345.12
Deduct 548 from 660 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 11:
If we divide 1120 by 274, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 292345.124
Subtracting 1096 from 1120 leaves us 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.

Advancing to step 12:
When dividing 240 by 274, we get 0 with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 292345.124
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
The number 274 fits into 2400 8 times, leaving a remainder of 208.
Use 8 as the next digit of our solution. 
Result so far: 292345.12408
Deduct 2192 from 2400 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 14:
274 can be fit into 2080 7 times, resulting in a remainder of 162.
Use 7 as the next digit of our solution. 
Result so far: 292345.124087
Subtract 1918 from 2080 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 15:
1620 divided by 274 is 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 292345.1240875
Deduct 1370 from 1620 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 16:
2500 divided by 274 is 9 with a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 292345.12408759
If we take 2466 away from 2500, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 292345.12408759 with a balance of 3.4e-08.
