Let's divide 623263 by 15
Let's see how many times 15 fits into 623263.

On to step 1:
When dividing 6 by 15, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 15

On to step 2:
If we divide 62 by 15, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 60 away from 62, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 15

Let's proceed to step 3:
23 divided by 15 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtracting 15 from 23 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 15

Moving on to step 4:
When dividing 82 by 15, we get 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 415.0
If we subtract 75 from 82, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 15

Advancing to step 5:
15 can be fit into 76 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 4155.0
The remainder is 1 after subtracting 75 from 76.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 15

Let's proceed to step 6:
15 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 41550.0
If we take 0 away from 13, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
130 divided by 15 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 41550.8
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 41550.86
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 41550.866
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 41550.866 and a remainder of 0.001.
