504209 divided by 4 
Let's see how many times 4 fits into 504209.

On to step 1:
If we divide 5 by 4, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 4 from 5 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 4

Moving on to step 2:
When dividing 10 by 4, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 12.0
If we take 8 away from 10, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 4

Moving on to step 3:
When dividing 24 by 4, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we take 24 away from 24, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 4

On to step 4:
2 divided by 4 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 1260.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 4

Let's proceed to step 5:
When dividing 20 by 4, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 12605.0
If we subtract 20 from 20, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 4

Let's proceed to step 6:
4 goes into 9 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 126052.0
Subtracting 8 from 9 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 4 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 126052.2
If we take 8 away from 10, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
20 divided by 4 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 126052.25
If we subtract 20 from 20, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 126052.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 126052.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 126052.25, with a leftover of 0.0.
