We look at the division of 936621 by 15 
We want to divide 936621 by 15.

On to step 1:
If we divide 9 by 15, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 15

Going ahead to step 2:
When dividing 93 by 15, we get 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 90 from 93 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 15

Moving on to step 3:
15 can be fit into 36 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 62.0
If we take 30 away from 36, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 15

Moving on to step 4:
15 goes into 66 4 times with a remainder of 6.
The next digit of our result is 4. 
Result so far: 624.0
Deduct 60 from 66 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 15

Step 5:
62 divided by 15 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 6244.0
If we subtract 60 from 62, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 15

Let's proceed to step 6:
15 can be fit into 21 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 62441.0
If we take 15 away from 21, we end up 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.

Moving on to step 7:
15 can be fit into 60 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 62441.4
If we take 60 away from 60, 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.

On to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 62441.4
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.

Moving on to step 9:
15 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 62441.4
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.

Our division results in 62441.4 with a remaining 0.0.
