We look at the division of 636626 by 15 
We want to divide 636626 by 15.

Advancing to step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 15

Going ahead to step 2:
15 goes into 63 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 60 from 63 leaves us with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 15

Going ahead to step 3:
If we divide 36 by 15, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 30 away from 36, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 15

Advancing to step 4:
If we divide 66 by 15, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 424.0
If we subtract 60 from 66, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 15

Let's proceed to step 5:
If we divide 62 by 15, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4244.0
Subtracting 60 from 62 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 15

Advancing to step 6:
If we divide 26 by 15, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 42441.0
If we take 15 away from 26, 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.

On to step 7:
The number 15 fits into 110 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 42441.7
If we subtract 105 from 110, 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.

Advancing to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 42441.73
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.

Advancing to step 9:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 42441.733
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 42441.733 with a balance of 0.0005.
