15271888 ÷ 299 
We want to figure out the number of times 15271888 can be divided by 299.

Moving on to step 1:
When dividing 1 by 299, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 299

Advancing to step 2:
15 divided by 299 is 0 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 (2) of the dividend behind the 15 and repeat the process: 152 / 299

Moving on to step 3:
If we divide 152 by 299, we get 0 and a remainder of 152.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 152, we get 152.
Include the next digit (7) from the dividend after 152, then repeat: 1527 / 299

Let's proceed to step 4:
1527 divided by 299 is 5 with a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 1495 from 1527 to get 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 299

Moving on to step 5:
299 can be fit into 321 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 51.0
If we take 299 away from 321, we end up with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 299

Advancing to step 6:
If we divide 228 by 299, we get 0 and a remainder of 228.
The number 0 becomes the next digit in our result. 
Result so far: 510.0
The remainder is 228 after subtracting 0 from 228.
Include the next digit (8) from the dividend after 228, then repeat: 2288 / 299

Moving on to step 7:
2288 divided by 299 is 7 with a remainder of 195.
Write down 7 as next digit of the result. 
Result so far: 5107.0
If we take 2093 away from 2288, we end up with 195.
Bring next digit (8) of the dividend behind the 195 and repeat the process: 1958 / 299

Moving on to step 8:
299 goes into 1958 6 times with a remainder of 164.
The next digit of our result is 6. 
Result so far: 51076.0
Deduct 1794 from 1958 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 9:
1640 divided by 299 is 5 with a remainder of 145.
The next digit of our result is 5. 
Result so far: 51076.5
Subtracting 1495 from 1640 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 10:
When dividing 1450 by 299, we get 4 with a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 51076.54
The remainder is 254 after subtracting 1196 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 11:
When dividing 2540 by 299, we get 8 with a remainder of 148.
Use 8 as the next digit of our solution. 
Result so far: 51076.548
Subtracting 2392 from 2540 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 12:
299 can be fit into 1480 4 times, resulting in a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 51076.5484
If we subtract 1196 from 1480, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 13:
299 goes into 2840 9 times with a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 51076.54849
Deduct 2691 from 2840 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 14:
299 can be fit into 1490 4 times, resulting in a remainder of 294.
The number 4 becomes the next digit in our result. 
Result so far: 51076.548494
Deduct 1196 from 1490 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 15:
The number 299 fits into 2940 9 times, leaving a remainder of 249.
Put 9 as the next digit of the answer. 
Result so far: 51076.5484949
Deduct 2691 from 2940 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 16:
When dividing 2490 by 299, we get 8 with a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 51076.54849498
Deduct 2392 from 2490 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The final outcome is 51076.54849498, with a leftover of 9.8e-08.
