We're dividing 939336 by 15 
We want to figure out the number of times 939336 can be divided by 15.

On to step 1:
9 divided by 15 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 15

Moving on to step 2:
15 can be fit into 93 6 times, resulting in a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 90 away from 93, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 15

Advancing to step 3:
15 goes into 39 2 times with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Deduct 30 from 39 and we're left with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 15

Step 4:
93 divided by 15 is 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 626.0
The remainder is 3 after subtracting 90 from 93.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 15

Advancing to step 5:
If we divide 33 by 15, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 6262.0
Subtract 30 from 33 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 15

Advancing to step 6:
15 can be fit into 36 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 62622.0
Deduct 30 from 36 and we're left with 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:
15 goes into 60 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 62622.4
If we subtract 60 from 60, 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:
0 divided by 15 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 62622.4
Deduct 0 from 0 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.

On to step 9:
15 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 62622.4
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.

After the division, we end up with 62622.4 and a remainder of 0.0.
