515533 divided by 285 
We're looking to find how many times 285 goes into 515533.

On to step 1:
The number 285 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 285

Step 2:
285 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 285

Step 3:
If we divide 515 by 285, we get 1 and a remainder of 230.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 285 from 515 to get 230.
Append the next digit (5) from the dividend to 230 and continue with: 2305 / 285

Moving on to step 4:
The number 285 fits into 2305 8 times, leaving a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 25 after subtracting 2280 from 2305.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 285

Step 5:
285 can be fit into 253 0 times, resulting in a remainder of 253.
Use 0 as the next digit of our solution. 
Result so far: 180.0
Subtract 0 from 253 to get 253.
Grab the next digit (3) from the dividend, add it to 253, then carry on: 2533 / 285

Let's proceed to step 6:
When dividing 2533 by 285, we get 8 with a remainder of 253.
Use 8 as the next digit of our solution. 
Result so far: 1808.0
The remainder is 253 after subtracting 2280 from 2533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 7:
The number 285 fits into 2530 8 times, leaving a remainder of 250.
Write down 8 as next digit of the result. 
Result so far: 1808.8
Deduct 2280 from 2530 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 8:
2500 divided by 285 is 8 with a remainder of 220.
The number 8 becomes the next digit in our result. 
Result so far: 1808.88
If we take 2280 away from 2500, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 1808.88 and a remainder of 0.22.
