Let's divide 53450189 by 728
We want to figure out the number of times 53450189 can be divided by 728.

On to step 1:
The number 728 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 728

Step 2:
If we divide 53 by 728, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 728

Advancing to step 3:
728 goes into 534 0 times with a remainder of 534.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 534 leaves us with 534.
Take the next digit (5) from the dividend and append it to 534, then repeat: 5345 / 728

On to step 4:
728 can be fit into 5345 7 times, resulting in a remainder of 249.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 5096 from 5345, we get 249.
Include the next digit (0) from the dividend after 249, then repeat: 2490 / 728

On to step 5:
2490 divided by 728 is 3 with a remainder of 306.
The next digit of our result is 3. 
Result so far: 73.0
If we subtract 2184 from 2490, we get 306.
Fetch the next digit (1) from the dividend, attach it to 306 and continue: 3061 / 728

Moving on to step 6:
The number 728 fits into 3061 4 times, leaving a remainder of 149.
The next digit of our result is 4. 
Result so far: 734.0
The remainder is 149 after subtracting 2912 from 3061.
Take the next digit (8) from the dividend and append it to 149, then repeat: 1498 / 728

Moving on to step 7:
When dividing 1498 by 728, we get 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 7342.0
Subtracting 1456 from 1498 leaves us with 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 728

Moving on to step 8:
If we divide 429 by 728, we get 0 and a remainder of 429.
Put 0 as the next digit of the answer. 
Result so far: 73420.0
If we subtract 0 from 429, we get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Let's proceed to step 9:
If we divide 4290 by 728, we get 5 and a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 73420.5
The remainder is 650 after subtracting 3640 from 4290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 10:
If we divide 6500 by 728, we get 8 and a remainder of 676.
Put 8 as the next digit of the answer. 
Result so far: 73420.58
Subtract 5824 from 6500 to get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Step 11:
728 goes into 6760 9 times with a remainder of 208.
Record the quotient 9 as the next digit in the result. 
Result so far: 73420.589
Subtracting 6552 from 6760 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 12:
If we divide 2080 by 728, we get 2 and a remainder of 624.
Record the quotient 2 as the next digit in the result. 
Result so far: 73420.5892
Deduct 1456 from 2080 and we're left with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 13:
728 can be fit into 6240 8 times, resulting in a remainder of 416.
Put 8 as the next digit of the answer. 
Result so far: 73420.58928
Subtract 5824 from 6240 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 14:
The number 728 fits into 4160 5 times, leaving a remainder of 520.
Write down 5 as next digit of the result. 
Result so far: 73420.589285
If we take 3640 away from 4160, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 15:
728 can be fit into 5200 7 times, resulting in a remainder of 104.
Use 7 as the next digit of our solution. 
Result so far: 73420.5892857
The remainder is 104 after subtracting 5096 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 16:
If we divide 1040 by 728, we get 1 and a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 73420.58928571
If we subtract 728 from 1040, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

In conclusion, the division gives 73420.58928571 with a balance of 3.12e-07.
