We look at the division of 936807 by 15 
We want to figure out the number of times 936807 can be divided by 15.

On to step 1:
15 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 15

On to step 2:
The number 15 fits into 93 6 times, leaving a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 90 from 93, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 15

Going ahead to step 3:
If we divide 36 by 15, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 62.0
The remainder is 6 after subtracting 30 from 36.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 15

Moving on to step 4:
If we divide 68 by 15, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 624.0
The remainder is 8 after subtracting 60 from 68.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 15

Step 5:
80 divided by 15 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6245.0
The remainder is 5 after subtracting 75 from 80.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 15

On to step 6:
If we divide 57 by 15, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 62453.0
Subtracting 45 from 57 leaves us 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.

On to step 7:
15 goes into 120 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 62453.8
Deduct 120 from 120 and we're left 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.

Moving on to step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 62453.8
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.

Going ahead to step 9:
0 divided by 15 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 62453.8
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 quotient of the division is 62453.8, and the remainder is 0.0.
