We look at the division of 515464 by 15 
We want to figure out the number of times 515464 can be divided by 15.

Going ahead to step 1:
The number 15 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 15

Step 2:
If we divide 51 by 15, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 45 from 51 leaves us with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 15

Let's proceed to step 3:
When dividing 65 by 15, we get 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we take 60 away from 65, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 15

Step 4:
15 goes into 54 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 343.0
The remainder is 9 after subtracting 45 from 54.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 15

Step 5:
If we divide 96 by 15, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 3436.0
If we subtract 90 from 96, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 15

Going ahead to step 6:
15 goes into 64 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 34364.0
Deduct 60 from 64 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.

On to step 7:
15 can be fit into 40 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 34364.2
If we take 30 away from 40, 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.

Moving on to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 34364.26
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.

Step 9:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 34364.266
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.

Our division results in 34364.266 with a remaining 0.001.
