33521 divided by 87 
We're looking to find how many times 87 goes into 33521.

Advancing to step 1:
87 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 87

Moving on to step 2:
If we divide 33 by 87, we get 0 and a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 87

On to step 3:
When dividing 335 by 87, we get 3 with a remainder of 74.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 261 from 335 and we're left with 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 87

Let's proceed to step 4:
When dividing 742 by 87, we get 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 46 after subtracting 696 from 742.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 87

Step 5:
If we divide 461 by 87, we get 5 and a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 385.0
If we take 435 away from 461, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 6:
87 can be fit into 260 2 times, resulting in a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 385.2
Subtract 174 from 260 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 7:
When dividing 860 by 87, we get 9 with a remainder of 77.
The next digit of our result is 9. 
Result so far: 385.29
The remainder is 77 after subtracting 783 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 8:
770 divided by 87 is 8 with a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 385.298
Subtracting 696 from 770 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 9:
87 goes into 740 8 times with a remainder of 44.
The next digit of our result is 8. 
Result so far: 385.2988
The remainder is 44 after subtracting 696 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 385.2988, and the remainder is 0.00044.
