Let's divide 1435621 by 728
We're looking to find how many times 728 goes into 1435621.

Going ahead to step 1:
728 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 728

Going ahead to step 2:
When dividing 14 by 728, we get 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 728

Step 3:
143 divided by 728 is 0 with a remainder of 143.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 143, we get 143.
Bring next digit (5) of the dividend behind the 143 and repeat the process: 1435 / 728

Moving on to step 4:
728 can be fit into 1435 1 times, resulting in a remainder of 707.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 728 from 1435 to get 707.
Grab the next digit (6) from the dividend, add it to 707, then carry on: 7076 / 728

Going ahead to step 5:
728 goes into 7076 9 times with a remainder of 524.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 524 after subtracting 6552 from 7076.
Bring next digit (2) of the dividend behind the 524 and repeat the process: 5242 / 728

Moving on to step 6:
If we divide 5242 by 728, we get 7 and a remainder of 146.
The next digit of our result is 7. 
Result so far: 197.0
Subtracting 5096 from 5242 leaves us with 146.
Fetch the next digit (1) from the dividend, attach it to 146 and continue: 1461 / 728

Advancing to step 7:
728 goes into 1461 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 1972.0
Subtracting 1456 from 1461 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
When dividing 50 by 728, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 1972.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
728 can be fit into 500 0 times, resulting in a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 1972.0
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 1972.0 and a remainder of 0.5.
