Let's divide 503186 by 15
We want to figure out the number of times 503186 can be divided by 15.

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
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 15

Step 2:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 5 after subtracting 45 from 50.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 15

Moving on to step 3:
The number 15 fits into 53 3 times, leaving a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we subtract 45 from 53, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 15

Going ahead to step 4:
The number 15 fits into 81 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 335.0
If we subtract 75 from 81, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 15

Step 5:
15 goes into 68 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 3354.0
If we subtract 60 from 68, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 15

Step 6:
15 goes into 86 5 times with a remainder of 11.
The next digit of our result is 5. 
Result so far: 33545.0
Subtracting 75 from 86 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
15 goes into 110 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 33545.7
Subtract 105 from 110 to 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.

Advancing 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: 33545.73
Subtract 45 from 50 to 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.

Let's proceed to step 9:
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: 33545.733
If we take 45 away from 50, 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.

In conclusion, the division gives 33545.733 with a balance of 0.0005.
