We look at the division of 636439 by 52 
Our goal is to divide 636439 by 52.

Moving on to step 1:
If we divide 6 by 52, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 52

Going ahead to step 2:
The number 52 fits into 63 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 52 from 63 leaves us with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 52

Moving on to step 3:
52 can be fit into 116 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 104 from 116 leaves us with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 52

Going ahead to step 4:
124 divided by 52 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we subtract 104 from 124, we get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 52

Let's proceed to step 5:
52 goes into 203 3 times with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 1223.0
Subtracting 156 from 203 leaves us with 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 52

On to step 6:
52 goes into 479 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 12239.0
If we subtract 468 from 479, we get 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 7:
110 divided by 52 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 12239.2
If we take 104 away from 110, we end up 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.

Let's proceed to step 8:
When dividing 60 by 52, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 12239.21
Subtracting 52 from 60 leaves us 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.

Advancing to step 9:
80 divided by 52 is 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 12239.211
Subtracting 52 from 80 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 12239.211 and a remainder of 0.0028.
