We divide 53538508 by 520
We want to figure out the number of times 53538508 can be divided by 520.

Going ahead to step 1:
520 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 520

Moving on to step 2:
The number 520 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 520

Step 3:
The number 520 fits into 535 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 520 from 535 to get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 520

On to step 4:
153 divided by 520 is 0 with a remainder of 153.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 153, we get 153.
Fetch the next digit (8) from the dividend, attach it to 153 and continue: 1538 / 520

On to step 5:
520 can be fit into 1538 2 times, resulting in a remainder of 498.
The next digit of our result is 2. 
Result so far: 102.0
Subtracting 1040 from 1538 leaves us with 498.
Include the next digit (5) from the dividend after 498, then repeat: 4985 / 520

On to step 6:
The number 520 fits into 4985 9 times, leaving a remainder of 305.
Record the quotient 9 as the next digit in the result. 
Result so far: 1029.0
Subtracting 4680 from 4985 leaves us with 305.
Fetch the next digit (0) from the dividend, attach it to 305 and continue: 3050 / 520

Let's proceed to step 7:
If we divide 3050 by 520, we get 5 and a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 10295.0
If we subtract 2600 from 3050, we get 450.
Append the next digit (8) from the dividend to 450 and continue with: 4508 / 520

Advancing to step 8:
520 goes into 4508 8 times with a remainder of 348.
Write down 8 as next digit of the result. 
Result so far: 102958.0
If we subtract 4160 from 4508, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 9:
520 goes into 3480 6 times with a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 102958.6
If we take 3120 away from 3480, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
3600 divided by 520 is 6 with a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 102958.66
Subtract 3120 from 3600 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 102958.66, with a leftover of 0.48.
