We're dividing 520368 by 452 
Let's see how many times 452 fits into 520368.

Step 1:
452 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 452

Going ahead to step 2:
If we divide 52 by 452, we get 0 and a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 452

Step 3:
452 goes into 520 1 times with a remainder of 68.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 452 from 520 and we're left with 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 452

Step 4:
The number 452 fits into 683 1 times, leaving a remainder of 231.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 452 from 683 leaves us with 231.
Bring next digit (6) of the dividend behind the 231 and repeat the process: 2316 / 452

Let's proceed to step 5:
If we divide 2316 by 452, we get 5 and a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 115.0
Subtract 2260 from 2316 to get 56.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 452

Going ahead to step 6:
The number 452 fits into 568 1 times, leaving a remainder of 116.
Write down 1 as next digit of the result. 
Result so far: 1151.0
If we subtract 452 from 568, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 7:
1160 divided by 452 is 2 with a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 1151.2
If we take 904 away from 1160, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 8:
2560 divided by 452 is 5 with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 1151.25
The remainder is 300 after subtracting 2260 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 9:
If we divide 3000 by 452, we get 6 and a remainder of 288.
Put 6 as the next digit of the answer. 
Result so far: 1151.256
If we take 2712 away from 3000, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 10:
452 goes into 2880 6 times with a remainder of 168.
Record the quotient 6 as the next digit in the result. 
Result so far: 1151.2566
If we subtract 2712 from 2880, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

After the division, we end up with 1151.2566 and a remainder of 0.00168.
