Let's divide 55239147 by 503
We're looking to find how many times 503 goes into 55239147.

Advancing to step 1:
5 divided by 503 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 503

On to step 2:
503 can be fit into 55 0 times, resulting in a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 503

Step 3:
552 divided by 503 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 503 away from 552, we end up with 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 503

Moving on to step 4:
When dividing 493 by 503, we get 0 with a remainder of 493.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 493 and we're left with 493.
Include the next digit (9) from the dividend after 493, then repeat: 4939 / 503

On to step 5:
When dividing 4939 by 503, we get 9 with a remainder of 412.
The next digit of our result is 9. 
Result so far: 109.0
The remainder is 412 after subtracting 4527 from 4939.
Grab the next digit (1) from the dividend, add it to 412, then carry on: 4121 / 503

On to step 6:
When dividing 4121 by 503, we get 8 with a remainder of 97.
Put 8 as the next digit of the answer. 
Result so far: 1098.0
If we subtract 4024 from 4121, we get 97.
Grab the next digit (4) from the dividend, add it to 97, then carry on: 974 / 503

Let's proceed to step 7:
When dividing 974 by 503, we get 1 with a remainder of 471.
The number 1 becomes the next digit in our result. 
Result so far: 10981.0
If we take 503 away from 974, we end up with 471.
Bring next digit (7) of the dividend behind the 471 and repeat the process: 4717 / 503

Step 8:
4717 divided by 503 is 9 with a remainder of 190.
Use 9 as the next digit of our solution. 
Result so far: 109819.0
Subtract 4527 from 4717 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 9:
503 can be fit into 1900 3 times, resulting in a remainder of 391.
Put 3 as the next digit of the answer. 
Result so far: 109819.3
If we take 1509 away from 1900, we end up with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Let's proceed to step 10:
503 can be fit into 3910 7 times, resulting in a remainder of 389.
The number 7 becomes the next digit in our result. 
Result so far: 109819.37
If we take 3521 away from 3910, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 11:
503 can be fit into 3890 7 times, resulting in a remainder of 369.
The number 7 becomes the next digit in our result. 
Result so far: 109819.377
Subtracting 3521 from 3890 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

After the division, we end up with 109819.377 and a remainder of 0.0369.
