152222 divided by 15 
We want to figure out the number of times 152222 can be divided by 15.

Let's proceed to step 1:
15 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 15

On to step 2:
The number 15 fits into 15 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 15 from 15, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 15

Moving on to step 3:
The number 15 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 2 to get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 15

On to step 4:
15 can be fit into 22 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtract 15 from 22 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 15

Step 5:
72 divided by 15 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1014.0
Subtracting 60 from 72 leaves us with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 15

Step 6:
15 goes into 122 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 10148.0
The remainder is 2 after subtracting 120 from 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 15, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 10148.1
The remainder is 5 after subtracting 15 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 10148.13
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 10148.133
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 10148.133 with a balance of 0.0005.
