545088 ÷ 15 
Let's see how many times 15 fits into 545088.

On to step 1:
When dividing 5 by 15, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 15

On to step 2:
If we divide 54 by 15, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 45 from 54 leaves us with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 15

Step 3:
The number 15 fits into 95 6 times, leaving a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtract 90 from 95 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 15

Going ahead to step 4:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 363.0
If we take 45 away from 50, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 15

Moving on to step 5:
If we divide 58 by 15, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3633.0
The remainder is 13 after subtracting 45 from 58.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 15

Moving on to step 6:
15 goes into 138 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 36339.0
Subtract 135 from 138 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
30 divided by 15 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 36339.2
Subtracting 30 from 30 leaves us with 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 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 36339.2
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 36339.2
Deduct 0 from 0 and we're left with 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 36339.2, with a leftover of 0.0.
