We divide 503629 by 42
We want to figure out the number of times 503629 can be divided by 42.

Going ahead to step 1:
5 divided by 42 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 42

Going ahead to step 2:
The number 42 fits into 50 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 42 from 50 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 42

Let's proceed to step 3:
42 goes into 83 1 times with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 41 after subtracting 42 from 83.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 42

Going ahead to step 4:
The number 42 fits into 416 9 times, leaving a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Subtracting 378 from 416 leaves us with 38.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 42

Step 5:
42 goes into 382 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 1199.0
Subtract 378 from 382 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 42

Step 6:
If we divide 49 by 42, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 11991.0
Subtracting 42 from 49 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 42, we get 1 and a remainder of 28.
The next digit of our result is 1. 
Result so far: 11991.1
Deduct 42 from 70 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
The number 42 fits into 280 6 times, leaving a remainder of 28.
The next digit of our result is 6. 
Result so far: 11991.16
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
The number 42 fits into 280 6 times, leaving a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 11991.166
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 11991.166, with a leftover of 0.0028.
