729453 divided by 4 
We're looking to find how many times 4 goes into 729453.

Going ahead to step 1:
When dividing 7 by 4, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 3 after subtracting 4 from 7.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 4

Advancing to step 2:
4 goes into 32 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 0 after subtracting 32 from 32.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 4

Going ahead to step 3:
If we divide 9 by 4, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 182.0
Deduct 8 from 9 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 4

Let's proceed to step 4:
4 can be fit into 14 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 1823.0
Deduct 12 from 14 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 4

Moving on to step 5:
25 divided by 4 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 18236.0
If we subtract 24 from 25, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 4

On to step 6:
4 can be fit into 13 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 182363.0
If we take 12 away from 13, we end up 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.

Let's proceed to step 7:
4 goes into 10 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 182363.2
Subtracting 8 from 10 leaves us 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.

Advancing to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 182363.25
The remainder is 0 after subtracting 20 from 20.
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 9:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 182363.25
If we subtract 0 from 0, 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 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 182363.25
Deduct 0 from 0 and we're left 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.

After the division, we end up with 182363.25 and a remainder of 0.0.
