When dividing 5 by 508, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 508

Going ahead to step 2:
508 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 508

Advancing to step 3:
508 goes into 516 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 8 after subtracting 508 from 516.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 508

Going ahead to step 4:
508 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 80 and we're left with 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 508

Advancing to step 5:
508 can be fit into 801 1 times, resulting in a remainder of 293.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtracting 508 from 801 leaves us with 293.
Bring next digit (6) of the dividend behind the 293 and repeat the process: 2936 / 508

Going ahead to step 6:
When dividing 2936 by 508, we get 5 with a remainder of 396.
Use 5 as the next digit of our solution. 
Result so far: 1015.0
Deduct 2540 from 2936 and we're left with 396.
Bring next digit (6) of the dividend behind the 396 and repeat the process: 3966 / 508

Step 7:
When dividing 3966 by 508, we get 7 with a remainder of 410.
The number 7 becomes the next digit in our result. 
Result so far: 10157.0
Subtract 3556 from 3966 to get 410.
Include the next digit (2) from the dividend after 410, then repeat: 4102 / 508

Advancing to step 8:
4102 divided by 508 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 101578.0
Subtracting 4064 from 4102 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
The number 508 fits into 380 0 times, leaving a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 101578.0
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 10:
The number 508 fits into 3800 7 times, leaving a remainder of 244.
Use 7 as the next digit of our solution. 
Result so far: 101578.07
Subtracting 3556 from 3800 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 11:
2440 divided by 508 is 4 with a remainder of 408.
Write down 4 as next digit of the result. 
Result so far: 101578.074
The remainder is 408 after subtracting 2032 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 12:
If we divide 4080 by 508, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 101578.0748
Deduct 4064 from 4080 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
508 goes into 160 0 times with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 101578.0748
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
508 goes into 1600 3 times with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 101578.074803
The remainder is 76 after subtracting 1524 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 15:
508 can be fit into 760 1 times, resulting in a remainder of 252.
Use 1 as the next digit of our solution. 
Result so far: 101578.0748031
If we subtract 508 from 760, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 16:
508 can be fit into 2520 4 times, resulting in a remainder of 488.
The number 4 becomes the next digit in our result. 
Result so far: 101578.07480314
The remainder is 488 after subtracting 2032 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final result is 101578.07480314 with a remainder of 4.88e-07.
