We're dividing 52450638 by 520 
We want to figure out the number of times 52450638 can be divided by 520.

Let's proceed to step 1:
520 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 520

Let's proceed to step 2:
520 goes into 52 0 times with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 520

On to step 3:
If we divide 524 by 520, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 520 from 524 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 520

Advancing to step 4:
520 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 520

Step 5:
When dividing 450 by 520, we get 0 with a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Subtracting 0 from 450 leaves us with 450.
Append the next digit (6) from the dividend to 450 and continue with: 4506 / 520

On to step 6:
When dividing 4506 by 520, we get 8 with a remainder of 346.
Put 8 as the next digit of the answer. 
Result so far: 1008.0
The remainder is 346 after subtracting 4160 from 4506.
Bring next digit (3) of the dividend behind the 346 and repeat the process: 3463 / 520

Step 7:
3463 divided by 520 is 6 with a remainder of 343.
The next digit of our result is 6. 
Result so far: 10086.0
Subtract 3120 from 3463 to get 343.
Take the next digit (8) from the dividend and append it to 343, then repeat: 3438 / 520

Let's proceed to step 8:
520 can be fit into 3438 6 times, resulting in a remainder of 318.
The next digit of our result is 6. 
Result so far: 100866.0
If we subtract 3120 from 3438, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 9:
The number 520 fits into 3180 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 100866.6
The remainder is 60 after subtracting 3120 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 520, we get 1 and a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 100866.61
Subtract 520 from 600 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
520 goes into 800 1 times with a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 100866.611
Subtracting 520 from 800 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Our division results in 100866.611 with a remaining 0.028.
