We divide 515299 by 15
Let's see how many times 15 fits into 515299.

Moving on to step 1:
5 divided by 15 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 15

Going ahead to step 2:
The number 15 fits into 51 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 45 away from 51, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 15

Advancing to step 3:
15 goes into 65 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 34.0
If we take 60 away from 65, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 15

Going ahead to step 4:
The number 15 fits into 52 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 343.0
Deduct 45 from 52 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 15

Moving on to step 5:
79 divided by 15 is 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 3435.0
Deduct 75 from 79 and we're left with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 15

Advancing to step 6:
If we divide 49 by 15, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 34353.0
Deduct 45 from 49 and we're left 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:
When dividing 40 by 15, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 34353.2
Subtract 30 from 40 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 8:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 34353.26
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 34353.266
Subtracting 90 from 100 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.

Our division results in 34353.266 with a remaining 0.001.
