15315008 ÷ 455 
Let's see how many times 455 fits into 15315008.

Going ahead to step 1:
When dividing 1 by 455, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 455

Advancing to step 2:
If we divide 15 by 455, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 455

Step 3:
If we divide 153 by 455, we get 0 and a remainder of 153.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 153, we get 153.
Fetch the next digit (1) from the dividend, attach it to 153 and continue: 1531 / 455

On to step 4:
1531 divided by 455 is 3 with a remainder of 166.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1365 from 1531 to get 166.
Include the next digit (5) from the dividend after 166, then repeat: 1665 / 455

Let's proceed to step 5:
1665 divided by 455 is 3 with a remainder of 300.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we take 1365 away from 1665, we end up with 300.
Append the next digit (0) from the dividend to 300 and continue with: 3000 / 455

Step 6:
455 goes into 3000 6 times with a remainder of 270.
Put 6 as the next digit of the answer. 
Result so far: 336.0
If we subtract 2730 from 3000, we get 270.
Bring next digit (0) of the dividend behind the 270 and repeat the process: 2700 / 455

On to step 7:
The number 455 fits into 2700 5 times, leaving a remainder of 425.
The next digit of our result is 5. 
Result so far: 3365.0
If we take 2275 away from 2700, we end up with 425.
Include the next digit (8) from the dividend after 425, then repeat: 4258 / 455

Moving on to step 8:
If we divide 4258 by 455, we get 9 and a remainder of 163.
Write down 9 as next digit of the result. 
Result so far: 33659.0
Subtracting 4095 from 4258 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 9:
455 can be fit into 1630 3 times, resulting in a remainder of 265.
The next digit of our result is 3. 
Result so far: 33659.3
Subtract 1365 from 1630 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 10:
When dividing 2650 by 455, we get 5 with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 33659.35
The remainder is 375 after subtracting 2275 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 11:
When dividing 3750 by 455, we get 8 with a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 33659.358
Deduct 3640 from 3750 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
1100 divided by 455 is 2 with a remainder of 190.
The next digit of our result is 2. 
Result so far: 33659.3582
Subtract 910 from 1100 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 13:
If we divide 1900 by 455, we get 4 and a remainder of 80.
The next digit of our result is 4. 
Result so far: 33659.35824
The remainder is 80 after subtracting 1820 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
455 can be fit into 800 1 times, resulting in a remainder of 345.
Use 1 as the next digit of our solution. 
Result so far: 33659.358241
Subtract 455 from 800 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 15:
455 goes into 3450 7 times with a remainder of 265.
Use 7 as the next digit of our solution. 
Result so far: 33659.3582417
Subtract 3185 from 3450 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 16:
455 goes into 2650 5 times with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 33659.35824175
The remainder is 375 after subtracting 2275 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Our division results in 33659.35824175 with a remaining 3.75e-07.
