We divide 45480790 by 15
We want to figure out the number of times 45480790 can be divided by 15.

Advancing to step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 15

Step 2:
15 can be fit into 45 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 45 away from 45, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 15

Moving on to step 3:
4 divided by 15 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 15

Let's proceed to step 4:
When dividing 48 by 15, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 303.0
If we subtract 45 from 48, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 15

On to step 5:
The number 15 fits into 30 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 3032.0
Subtract 30 from 30 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 15

Let's proceed to step 6:
When dividing 7 by 15, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 30320.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 15

Let's proceed to step 7:
79 divided by 15 is 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 303205.0
Subtracting 75 from 79 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 15

On to step 8:
When dividing 40 by 15, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 3032052.0
If we subtract 30 from 40, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 3032052.6
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 15, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 3032052.66
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 3032052.66, with a leftover of 0.01.
