53012 divided by 15 
We want to divide 53012 by 15.

Let's proceed to step 1:
When dividing 5 by 15, we get 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.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 15

On to step 2:
15 can be fit into 53 3 times, resulting in a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 45 from 53 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 15

Let's proceed to step 3:
80 divided by 15 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 35.0
Deduct 75 from 80 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 15

Step 4:
15 can be fit into 51 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 353.0
If we subtract 45 from 51, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 15

Let's proceed to step 5:
15 goes into 62 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 3534.0
Subtracting 60 from 62 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 6:
15 goes into 20 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 3534.1
Subtracting 15 from 20 leaves us 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.

On to step 7:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3534.13
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.

Let's proceed to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3534.133
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.

The final result is 3534.133 with a remainder of 0.0005.
