We look at the division of 622616 by 15 
We want to figure out the number of times 622616 can be divided by 15.

Step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 15

Let's proceed to step 2:
If we divide 62 by 15, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 60 from 62 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 15

Advancing to step 3:
The number 15 fits into 22 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 15 from 22 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 15

Advancing to step 4:
76 divided by 15 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 415.0
If we subtract 75 from 76, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 15

Advancing to step 5:
If we divide 11 by 15, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 4150.0
Deduct 0 from 11 and we're left with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 15

Advancing to step 6:
116 divided by 15 is 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 41507.0
If we take 105 away from 116, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
15 goes into 110 7 times with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 41507.7
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 41507.73
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 41507.733
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 41507.733 with a remaining 0.0005.
