We look at the division of 15077451 by 277 
Let's see how many times 277 fits into 15077451.

Going ahead to step 1:
When dividing 1 by 277, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 277

On to step 2:
277 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 277

Advancing to step 3:
The number 277 fits into 150 0 times, leaving a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 150 to get 150.
Grab the next digit (7) from the dividend, add it to 150, then carry on: 1507 / 277

Step 4:
277 goes into 1507 5 times with a remainder of 122.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 1385 away from 1507, we end up with 122.
Append the next digit (7) from the dividend to 122 and continue with: 1227 / 277

On to step 5:
277 goes into 1227 4 times with a remainder of 119.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtract 1108 from 1227 to get 119.
Grab the next digit (4) from the dividend, add it to 119, then carry on: 1194 / 277

On to step 6:
277 can be fit into 1194 4 times, resulting in a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 544.0
Deduct 1108 from 1194 and we're left with 86.
Fetch the next digit (5) from the dividend, attach it to 86 and continue: 865 / 277

Step 7:
When dividing 865 by 277, we get 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 5443.0
Deduct 831 from 865 and we're left with 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 277

Moving on to step 8:
When dividing 341 by 277, we get 1 with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 54431.0
Deduct 277 from 341 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
640 divided by 277 is 2 with a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 54431.2
Subtracting 554 from 640 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 10:
The number 277 fits into 860 3 times, leaving a remainder of 29.
The next digit of our result is 3. 
Result so far: 54431.23
Deduct 831 from 860 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
290 divided by 277 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 54431.231
Subtracting 277 from 290 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
If we divide 130 by 277, we get 0 and a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 54431.231
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 13:
277 goes into 1300 4 times with a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 54431.23104
Subtract 1108 from 1300 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 14:
277 goes into 1920 6 times with a remainder of 258.
The number 6 becomes the next digit in our result. 
Result so far: 54431.231046
Subtracting 1662 from 1920 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 15:
277 goes into 2580 9 times with a remainder of 87.
Put 9 as the next digit of the answer. 
Result so far: 54431.2310469
If we subtract 2493 from 2580, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 16:
The number 277 fits into 870 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 54431.23104693
Subtract 831 from 870 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 54431.23104693, with a leftover of 3.9e-08.
