Let's divide 518512 by 15
We want to figure out the number of times 518512 can be divided by 15.

Let's proceed to step 1:
When dividing 5 by 15, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 15

Moving on to step 2:
15 can be fit into 51 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 45 from 51 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 15

Going ahead to step 3:
When dividing 68 by 15, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 34.0
Deduct 60 from 68 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 15

Advancing to step 4:
If we divide 85 by 15, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 345.0
If we subtract 75 from 85, we get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 15

Step 5:
The number 15 fits into 101 6 times, leaving a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 3456.0
If we subtract 90 from 101, we get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 15

Step 6:
If we divide 112 by 15, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 34567.0
The remainder is 7 after subtracting 105 from 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
When dividing 70 by 15, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 34567.4
If we subtract 60 from 70, 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.

Let's proceed to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 34567.46
Deduct 90 from 100 and we're left 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.

Moving on to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 34567.466
Deduct 90 from 100 and we're left 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.

The final outcome is 34567.466, with a leftover of 0.001.
