22857 divided by 15 
We want to figure out the number of times 22857 can be divided by 15.

Step 1:
15 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 15

Let's proceed to step 2:
22 divided by 15 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 15 from 22 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 15

Moving on to step 3:
78 divided by 15 is 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 75 away from 78, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 15

Let's proceed to step 4:
15 goes into 35 2 times with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Subtract 30 from 35 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 15

Step 5:
When dividing 57 by 15, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 1523.0
Deduct 45 from 57 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 6:
15 can be fit into 120 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1523.8
If we take 120 away from 120, we end up 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.

Let's proceed to step 7:
15 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1523.8
If we take 0 away from 0, we end up 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.

Going ahead to step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1523.8
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.

The final outcome is 1523.8, with a leftover of 0.0.
