We're dividing 503249 by 4 
We're looking to find how many times 4 goes into 503249.

On to step 1:
When dividing 5 by 4, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 4 from 5 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 4

Advancing to step 2:
4 goes into 10 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 8 away from 10, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 4

Step 3:
The number 4 fits into 23 5 times, leaving a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
If we take 20 away from 23, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 4

Advancing to step 4:
If we divide 32 by 4, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 1258.0
If we subtract 32 from 32, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 4

Advancing to step 5:
The number 4 fits into 4 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 12581.0
Deduct 4 from 4 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 4

Let's proceed to step 6:
4 goes into 9 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 125812.0
Deduct 8 from 9 and we're left 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.

Step 7:
The number 4 fits into 10 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 125812.2
The remainder is 2 after subtracting 8 from 10.
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:
When dividing 20 by 4, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 125812.25
Subtracting 20 from 20 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.

Advancing to step 9:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 125812.25
If we take 0 away from 0, we end up 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.

On to step 10:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 125812.25
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 result is 125812.25 with a remainder of 0.0.
