We're dividing 285621 by 52 
We want to figure out the number of times 285621 can be divided by 52.

Step 1:
When dividing 2 by 52, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 52

Step 2:
52 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 52

Step 3:
52 goes into 285 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 25 after subtracting 260 from 285.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 52

Going ahead to step 4:
When dividing 256 by 52, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtracting 208 from 256 leaves us with 48.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 52

Step 5:
If we divide 482 by 52, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 549.0
Subtract 468 from 482 to get 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 52

On to step 6:
52 goes into 141 2 times with a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 5492.0
The remainder is 37 after subtracting 104 from 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
When dividing 370 by 52, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 5492.7
Subtracting 364 from 370 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 52, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 5492.71
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
52 can be fit into 80 1 times, resulting in a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 5492.711
The remainder is 28 after subtracting 52 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 5492.711, with a leftover of 0.0028.
