445807 ÷ 15 
We're looking to find how many times 15 goes into 445807.

On to step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 15

Advancing to step 2:
The number 15 fits into 44 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 30 from 44 leaves us with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 15

Step 3:
145 divided by 15 is 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtract 135 from 145 to get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 15

Going ahead to step 4:
When dividing 108 by 15, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 297.0
If we subtract 105 from 108, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 15

Let's proceed to step 5:
30 divided by 15 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2972.0
If we take 30 away from 30, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 15

On to step 6:
The number 15 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 29720.0
If we subtract 0 from 7, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 15, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 29720.4
Deduct 60 from 70 and we're left 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.

Moving on to step 8:
15 goes into 100 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 29720.46
If we subtract 90 from 100, 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.

Advancing to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 29720.466
If we subtract 90 from 100, 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.

Our division results in 29720.466 with a remaining 0.001.
