15268817 ÷ 454 
We're looking to find how many times 454 goes into 15268817.

Let's proceed to step 1:
When dividing 1 by 454, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 454

Step 2:
15 divided by 454 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 454

Step 3:
If we divide 152 by 454, we get 0 and a remainder of 152.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 152 and we're left with 152.
Grab the next digit (6) from the dividend, add it to 152, then carry on: 1526 / 454

Let's proceed to step 4:
454 goes into 1526 3 times with a remainder of 164.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1362 from 1526 to get 164.
Grab the next digit (8) from the dividend, add it to 164, then carry on: 1648 / 454

On to step 5:
The number 454 fits into 1648 3 times, leaving a remainder of 286.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 1362 away from 1648, we end up with 286.
Take the next digit (8) from the dividend and append it to 286, then repeat: 2868 / 454

Moving on to step 6:
The number 454 fits into 2868 6 times, leaving a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 336.0
If we take 2724 away from 2868, we end up with 144.
Grab the next digit (1) from the dividend, add it to 144, then carry on: 1441 / 454

Moving on to step 7:
1441 divided by 454 is 3 with a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 3363.0
Subtracting 1362 from 1441 leaves us with 79.
Append the next digit (7) from the dividend to 79 and continue with: 797 / 454

Going ahead to step 8:
454 can be fit into 797 1 times, resulting in a remainder of 343.
Put 1 as the next digit of the answer. 
Result so far: 33631.0
If we subtract 454 from 797, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 9:
When dividing 3430 by 454, we get 7 with a remainder of 252.
Use 7 as the next digit of our solution. 
Result so far: 33631.7
Deduct 3178 from 3430 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 10:
If we divide 2520 by 454, we get 5 and a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 33631.75
If we take 2270 away from 2520, we end up 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.

On to step 11:
454 can be fit into 2500 5 times, resulting in a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 33631.755
Deduct 2270 from 2500 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

After the division, we end up with 33631.755 and a remainder of 0.023.
