We divide 455274 by 15
We want to figure out the number of times 455274 can be divided by 15.

Moving on to step 1:
4 divided by 15 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 15

Advancing to step 2:
15 can be fit into 45 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 45 from 45, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 15

Advancing to step 3:
The number 15 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 15

Advancing to step 4:
15 can be fit into 52 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 303.0
If we take 45 away from 52, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 15

Going ahead to step 5:
If we divide 77 by 15, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 3035.0
Deduct 75 from 77 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 15

Going ahead to step 6:
The number 15 fits into 24 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 30351.0
Subtract 15 from 24 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 15, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 30351.6
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30351.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 15, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30351.6
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 30351.6, with a leftover of 0.0.
