We look at the division of 755555 by 15 
We're looking to find how many times 15 goes into 755555.

On to step 1:
The number 15 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 15

Step 2:
When dividing 75 by 15, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 75 from 75 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 15

On to step 3:
5 divided by 15 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 15

Step 4:
When dividing 55 by 15, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 503.0
If we take 45 away from 55, we end up with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 15

Step 5:
The number 15 fits into 105 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 5037.0
The remainder is 0 after subtracting 105 from 105.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 15

On to step 6:
15 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 50370.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 50370.3
Subtract 45 from 50 to 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:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 50370.33
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.

The final outcome is 50370.33, with a leftover of 0.005.
