We look at the division of 504469 by 42 
We want to figure out the number of times 504469 can be divided by 42.

Advancing to step 1:
When dividing 5 by 42, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 42

Moving on to step 2:
When dividing 50 by 42, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 42 away from 50, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 42

Advancing to step 3:
42 goes into 84 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 84 away from 84, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 42

On to step 4:
When dividing 4 by 42, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 120.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 42

Let's proceed to step 5:
When dividing 46 by 42, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1201.0
Subtract 42 from 46 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 42

Going ahead to step 6:
42 goes into 49 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 12011.0
Subtract 42 from 49 to get 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:
70 divided by 42 is 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 12011.1
The remainder is 28 after subtracting 42 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
280 divided by 42 is 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 12011.16
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
42 goes into 280 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 12011.166
Deduct 252 from 280 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.

The final outcome is 12011.166, with a leftover of 0.0028.
