We look at the division of 12986653 by 508 
We want to figure out the number of times 12986653 can be divided by 508.

Step 1:
1 divided by 508 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 508

Moving on to step 2:
12 divided by 508 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 508

Going ahead to step 3:
If we divide 129 by 508, we get 0 and a remainder of 129.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 129, we end up with 129.
Append the next digit (8) from the dividend to 129 and continue with: 1298 / 508

Advancing to step 4:
The number 508 fits into 1298 2 times, leaving a remainder of 282.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1016 from 1298 leaves us with 282.
Bring next digit (6) of the dividend behind the 282 and repeat the process: 2826 / 508

Going ahead to step 5:
508 goes into 2826 5 times with a remainder of 286.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 2540 from 2826 leaves us with 286.
Grab the next digit (6) from the dividend, add it to 286, then carry on: 2866 / 508

Let's proceed to step 6:
508 goes into 2866 5 times with a remainder of 326.
Use 5 as the next digit of our solution. 
Result so far: 255.0
Deduct 2540 from 2866 and we're left with 326.
Bring next digit (5) of the dividend behind the 326 and repeat the process: 3265 / 508

Step 7:
3265 divided by 508 is 6 with a remainder of 217.
Use 6 as the next digit of our solution. 
Result so far: 2556.0
The remainder is 217 after subtracting 3048 from 3265.
Include the next digit (3) from the dividend after 217, then repeat: 2173 / 508

Let's proceed to step 8:
508 can be fit into 2173 4 times, resulting in a remainder of 141.
Use 4 as the next digit of our solution. 
Result so far: 25564.0
The remainder is 141 after subtracting 2032 from 2173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 9:
508 goes into 1410 2 times with a remainder of 394.
The number 2 becomes the next digit in our result. 
Result so far: 25564.2
The remainder is 394 after subtracting 1016 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 10:
If we divide 3940 by 508, we get 7 and a remainder of 384.
The number 7 becomes the next digit in our result. 
Result so far: 25564.27
Deduct 3556 from 3940 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 11:
508 goes into 3840 7 times with a remainder of 284.
Put 7 as the next digit of the answer. 
Result so far: 25564.277
The remainder is 284 after subtracting 3556 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The final result is 25564.277 with a remainder of 0.0284.
