We look at the division of 68666855 by 503 
We're looking to find how many times 503 goes into 68666855.

Moving on to step 1:
When dividing 6 by 503, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 503

Going ahead to step 2:
If we divide 68 by 503, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 503

Moving on to step 3:
When dividing 686 by 503, we get 1 with a remainder of 183.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 503 from 686 and we're left with 183.
Grab the next digit (6) from the dividend, add it to 183, then carry on: 1836 / 503

Advancing to step 4:
503 can be fit into 1836 3 times, resulting in a remainder of 327.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1509 from 1836 leaves us with 327.
Bring next digit (6) of the dividend behind the 327 and repeat the process: 3276 / 503

Moving on to step 5:
When dividing 3276 by 503, we get 6 with a remainder of 258.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Subtract 3018 from 3276 to get 258.
Append the next digit (8) from the dividend to 258 and continue with: 2588 / 503

Going ahead to step 6:
If we divide 2588 by 503, we get 5 and a remainder of 73.
Use 5 as the next digit of our solution. 
Result so far: 1365.0
Deduct 2515 from 2588 and we're left with 73.
Bring next digit (5) of the dividend behind the 73 and repeat the process: 735 / 503

Advancing to step 7:
The number 503 fits into 735 1 times, leaving a remainder of 232.
Write down 1 as next digit of the result. 
Result so far: 13651.0
Subtracting 503 from 735 leaves us with 232.
Fetch the next digit (5) from the dividend, attach it to 232 and continue: 2325 / 503

Moving on to step 8:
When dividing 2325 by 503, we get 4 with a remainder of 313.
Record the quotient 4 as the next digit in the result. 
Result so far: 136514.0
Subtract 2012 from 2325 to get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Let's proceed to step 9:
The number 503 fits into 3130 6 times, leaving a remainder of 112.
The next digit of our result is 6. 
Result so far: 136514.6
Subtract 3018 from 3130 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 10:
If we divide 1120 by 503, we get 2 and a remainder of 114.
Use 2 as the next digit of our solution. 
Result so far: 136514.62
If we take 1006 away from 1120, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 11:
If we divide 1140 by 503, we get 2 and a remainder of 134.
Use 2 as the next digit of our solution. 
Result so far: 136514.622
Deduct 1006 from 1140 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The final outcome is 136514.622, with a leftover of 0.0134.
