Let's divide 503720 by 42
We want to figure out the number of times 503720 can be divided by 42.

On to step 1:
The number 42 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 42

Step 2:
50 divided by 42 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 42 from 50 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 42

Step 3:
42 can be fit into 83 1 times, resulting in a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 42 from 83, we get 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 42

Going ahead to step 4:
42 goes into 417 9 times with a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Subtract 378 from 417 to get 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 42

On to step 5:
42 goes into 392 9 times with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 1199.0
Subtracting 378 from 392 leaves us with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 42

Step 6:
When dividing 140 by 42, we get 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 11993.0
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
When dividing 140 by 42, we get 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 11993.3
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
The number 42 fits into 140 3 times, leaving a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 11993.33
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 11993.33 and a remainder of 0.014.
