We're dividing 758554 by 15 
We're looking to find how many times 15 goes into 758554.

Let's proceed to step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 15

Let's proceed to step 2:
The number 15 fits into 75 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 0 after subtracting 75 from 75.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 15

Moving on to step 3:
If we divide 8 by 15, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 15

On to step 4:
When dividing 85 by 15, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 505.0
Subtract 75 from 85 to get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 15

On to step 5:
The number 15 fits into 105 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 5057.0
If we take 105 away from 105, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 15

On to step 6:
4 divided by 15 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 50570.0
If we take 0 away from 4, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
15 can be fit into 40 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 50570.2
Subtracting 30 from 40 leaves us 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.

Advancing to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 50570.26
Subtract 90 from 100 to 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:
If we divide 100 by 15, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 50570.266
Subtract 90 from 100 to 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.

The final outcome is 50570.266, with a leftover of 0.001.
