We look at the division of 729168 by 4 
We want to figure out the number of times 729168 can be divided by 4.

On to step 1:
The number 4 fits into 7 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 4 from 7 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 4

Moving on to step 2:
When dividing 32 by 4, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 32 from 32 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 4

Moving on to step 3:
4 can be fit into 9 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 182.0
If we subtract 8 from 9, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 4

Advancing to step 4:
When dividing 11 by 4, we get 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 1822.0
If we take 8 away from 11, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 4

Advancing to step 5:
When dividing 36 by 4, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 18229.0
Subtracting 36 from 36 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 4

On to step 6:
When dividing 8 by 4, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 182292.0
Deduct 8 from 8 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.

On to step 7:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 182292.0
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.

Advancing to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 182292.0
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.

After the division, we end up with 182292.0 and a remainder of 0.0.
