42754581 ÷ 503 
We're looking to find how many times 503 goes into 42754581.

Going ahead to step 1:
503 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 503

Advancing to step 2:
The number 503 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 503

On to step 3:
427 divided by 503 is 0 with a remainder of 427.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 427 and we're left with 427.
Bring next digit (5) of the dividend behind the 427 and repeat the process: 4275 / 503

Moving on to step 4:
503 goes into 4275 8 times with a remainder of 251.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 4024 from 4275, we get 251.
Include the next digit (4) from the dividend after 251, then repeat: 2514 / 503

Step 5:
2514 divided by 503 is 4 with a remainder of 502.
Write down 4 as next digit of the result. 
Result so far: 84.0
The remainder is 502 after subtracting 2012 from 2514.
Append the next digit (5) from the dividend to 502 and continue with: 5025 / 503

Step 6:
If we divide 5025 by 503, we get 9 and a remainder of 498.
Use 9 as the next digit of our solution. 
Result so far: 849.0
Deduct 4527 from 5025 and we're left with 498.
Take the next digit (8) from the dividend and append it to 498, then repeat: 4988 / 503

Going ahead to step 7:
503 can be fit into 4988 9 times, resulting in a remainder of 461.
Use 9 as the next digit of our solution. 
Result so far: 8499.0
Deduct 4527 from 4988 and we're left with 461.
Fetch the next digit (1) from the dividend, attach it to 461 and continue: 4611 / 503

On to step 8:
503 can be fit into 4611 9 times, resulting in a remainder of 84.
The next digit of our result is 9. 
Result so far: 84999.0
The remainder is 84 after subtracting 4527 from 4611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 9:
840 divided by 503 is 1 with a remainder of 337.
Record the quotient 1 as the next digit in the result. 
Result so far: 84999.1
Subtracting 503 from 840 leaves us with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

On to step 10:
503 goes into 3370 6 times with a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 84999.16
Subtract 3018 from 3370 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 11:
The number 503 fits into 3520 6 times, leaving a remainder of 502.
Use 6 as the next digit of our solution. 
Result so far: 84999.166
The remainder is 502 after subtracting 3018 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

The final outcome is 84999.166, with a leftover of 0.0502.
