207957 ÷ 15 
Let's see how many times 15 fits into 207957.

Step 1:
15 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 15

Advancing to step 2:
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: 1.0
Deduct 15 from 20 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 15

Moving on to step 3:
If we divide 57 by 15, we get 3 and a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 45 away from 57, we end up with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 15

Let's proceed to step 4:
129 divided by 15 is 8 with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
If we subtract 120 from 129, we get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 15

Moving on to step 5:
The number 15 fits into 95 6 times, leaving a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 1386.0
Subtract 90 from 95 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 15

Step 6:
15 goes into 57 3 times with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 13863.0
If we subtract 45 from 57, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
15 goes into 120 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 13863.8
If we subtract 120 from 120, we 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.

Step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13863.8
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.

Advancing to step 9:
15 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13863.8
Subtracting 0 from 0 leaves us 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.

The final result is 13863.8 with a remainder of 0.0.
