51685708 divided by 503 
We want to figure out the number of times 51685708 can be divided by 503.

Going ahead to step 1:
503 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 503

Going ahead to step 2:
503 goes into 51 0 times with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 503

On to step 3:
If we divide 516 by 503, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 13 after subtracting 503 from 516.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 503

Step 4:
138 divided by 503 is 0 with a remainder of 138.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 138 leaves us with 138.
Include the next digit (5) from the dividend after 138, then repeat: 1385 / 503

Step 5:
503 can be fit into 1385 2 times, resulting in a remainder of 379.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Deduct 1006 from 1385 and we're left with 379.
Append the next digit (7) from the dividend to 379 and continue with: 3797 / 503

Advancing to step 6:
503 can be fit into 3797 7 times, resulting in a remainder of 276.
Record the quotient 7 as the next digit in the result. 
Result so far: 1027.0
Subtracting 3521 from 3797 leaves us with 276.
Append the next digit (0) from the dividend to 276 and continue with: 2760 / 503

Moving on to step 7:
503 goes into 2760 5 times with a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 10275.0
If we take 2515 away from 2760, we end up with 245.
Take the next digit (8) from the dividend and append it to 245, then repeat: 2458 / 503

Moving on to step 8:
The number 503 fits into 2458 4 times, leaving a remainder of 446.
The next digit of our result is 4. 
Result so far: 102754.0
Deduct 2012 from 2458 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Going ahead to step 9:
If we divide 4460 by 503, we get 8 and a remainder of 436.
Record the quotient 8 as the next digit in the result. 
Result so far: 102754.8
If we take 4024 away from 4460, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 10:
503 goes into 4360 8 times with a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 102754.88
The remainder is 336 after subtracting 4024 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

In conclusion, the division gives 102754.88 with a balance of 0.336.
