We look at the division of 80172566 by 277 
We want to figure out the number of times 80172566 can be divided by 277.

Step 1:
If we divide 8 by 277, we get 0 and 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.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 277

Let's proceed to step 2:
277 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 277

Advancing to step 3:
If we divide 801 by 277, we get 2 and a remainder of 247.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 554 from 801 to get 247.
Take the next digit (7) from the dividend and append it to 247, then repeat: 2477 / 277

Moving on to step 4:
277 can be fit into 2477 8 times, resulting in a remainder of 261.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 2216 from 2477 leaves us with 261.
Grab the next digit (2) from the dividend, add it to 261, then carry on: 2612 / 277

Advancing to step 5:
The number 277 fits into 2612 9 times, leaving a remainder of 119.
Write down 9 as next digit of the result. 
Result so far: 289.0
If we subtract 2493 from 2612, we get 119.
Fetch the next digit (5) from the dividend, attach it to 119 and continue: 1195 / 277

Going ahead to step 6:
277 goes into 1195 4 times with a remainder of 87.
Record the quotient 4 as the next digit in the result. 
Result so far: 2894.0
Deduct 1108 from 1195 and we're left with 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 277

On to step 7:
277 goes into 876 3 times with a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 28943.0
The remainder is 45 after subtracting 831 from 876.
Grab the next digit (6) from the dividend, add it to 45, then carry on: 456 / 277

Advancing to step 8:
When dividing 456 by 277, we get 1 with a remainder of 179.
Write down 1 as next digit of the result. 
Result so far: 289431.0
If we take 277 away from 456, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 9:
1790 divided by 277 is 6 with a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 289431.6
Subtracting 1662 from 1790 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 10:
277 goes into 1280 4 times with a remainder of 172.
The number 4 becomes the next digit in our result. 
Result so far: 289431.64
Subtract 1108 from 1280 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
277 goes into 1720 6 times with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 289431.646
Subtracting 1662 from 1720 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
When dividing 580 by 277, we get 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 289431.6462
Subtract 554 from 580 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
260 divided by 277 is 0 with a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 289431.6462
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 14:
277 goes into 2600 9 times with a remainder of 107.
Write down 9 as next digit of the result. 
Result so far: 289431.646209
Subtract 2493 from 2600 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 15:
1070 divided by 277 is 3 with a remainder of 239.
The number 3 becomes the next digit in our result. 
Result so far: 289431.6462093
Subtracting 831 from 1070 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 16:
277 goes into 2390 8 times with a remainder of 174.
The number 8 becomes the next digit in our result. 
Result so far: 289431.64620938
Subtracting 2216 from 2390 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The final result is 289431.64620938 with a remainder of 1.74e-07.
