We're dividing 722256 by 15 
We're looking to find how many times 15 goes into 722256.

Moving on to step 1:
15 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 15

Moving on to step 2:
15 goes into 72 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 60 from 72 leaves us with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 15

Step 3:
If we divide 122 by 15, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 48.0
If we subtract 120 from 122, we get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 15

Step 4:
The number 15 fits into 22 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 481.0
Subtract 15 from 22 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 15

Advancing to step 5:
75 divided by 15 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4815.0
Deduct 75 from 75 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 15

On to step 6:
15 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 48150.0
The remainder is 6 after subtracting 0 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 15 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 48150.4
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 48150.4
The remainder is 0 after subtracting 0 from 0.
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 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 48150.4
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.

The quotient of the division is 48150.4, and the remainder is 0.0.
