We divide 33521 by 15
We want to figure out the number of times 33521 can be divided by 15.

On to step 1:
When dividing 3 by 15, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 15

On to step 2:
If we divide 33 by 15, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 3 after subtracting 30 from 33.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 15

Let's proceed to step 3:
When dividing 35 by 15, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 30 away from 35, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 15

On to step 4:
52 divided by 15 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 223.0
Subtract 45 from 52 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 15

Let's proceed to step 5:
71 divided by 15 is 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 2234.0
Subtracting 60 from 71 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.

On to step 6:
110 divided by 15 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 2234.7
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.

Moving on to step 7:
15 goes into 50 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 2234.73
Subtracting 45 from 50 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.

Advancing to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 2234.733
Subtracting 45 from 50 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.

The final outcome is 2234.733, with a leftover of 0.0005.
