We divide 13678972 by 503
We want to figure out the number of times 13678972 can be divided by 503.

Step 1:
1 divided by 503 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 503

Moving on to step 2:
503 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 503

Going ahead to step 3:
When dividing 136 by 503, we get 0 with a remainder of 136.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 136 leaves us with 136.
Bring next digit (7) of the dividend behind the 136 and repeat the process: 1367 / 503

Advancing to step 4:
The number 503 fits into 1367 2 times, leaving a remainder of 361.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1006 from 1367 leaves us with 361.
Fetch the next digit (8) from the dividend, attach it to 361 and continue: 3618 / 503

Step 5:
503 can be fit into 3618 7 times, resulting in a remainder of 97.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 3521 from 3618 leaves us with 97.
Grab the next digit (9) from the dividend, add it to 97, then carry on: 979 / 503

On to step 6:
The number 503 fits into 979 1 times, leaving a remainder of 476.
The next digit of our result is 1. 
Result so far: 271.0
Subtract 503 from 979 to get 476.
Bring next digit (7) of the dividend behind the 476 and repeat the process: 4767 / 503

Going ahead to step 7:
When dividing 4767 by 503, we get 9 with a remainder of 240.
Use 9 as the next digit of our solution. 
Result so far: 2719.0
The remainder is 240 after subtracting 4527 from 4767.
Include the next digit (2) from the dividend after 240, then repeat: 2402 / 503

Step 8:
2402 divided by 503 is 4 with a remainder of 390.
Use 4 as the next digit of our solution. 
Result so far: 27194.0
Deduct 2012 from 2402 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 9:
If we divide 3900 by 503, we get 7 and a remainder of 379.
Write down 7 as next digit of the result. 
Result so far: 27194.7
If we subtract 3521 from 3900, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 10:
If we divide 3790 by 503, we get 7 and a remainder of 269.
The next digit of our result is 7. 
Result so far: 27194.77
Deduct 3521 from 3790 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

The final outcome is 27194.77, with a leftover of 0.269.
