We look at the division of 516293 by 15 
We want to figure out the number of times 516293 can be divided by 15.

Advancing to step 1:
5 divided by 15 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 15

Advancing to step 2:
15 goes into 51 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 6 after subtracting 45 from 51.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 15

On to step 3:
15 can be fit into 66 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we subtract 60 from 66, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 15

Advancing to step 4:
15 can be fit into 62 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 344.0
Deduct 60 from 62 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 15

Step 5:
If we divide 29 by 15, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 3441.0
The remainder is 14 after subtracting 15 from 29.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 15

Advancing to step 6:
15 can be fit into 143 9 times, resulting in a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 34419.0
The remainder is 8 after subtracting 135 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
15 can be fit into 80 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 34419.5
If we take 75 away from 80, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 34419.53
The remainder is 5 after subtracting 45 from 50.
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 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 34419.533
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 quotient of the division is 34419.533, and the remainder is 0.0005.
