90009254 ÷ 728 
Let's see how many times 728 fits into 90009254.

Let's proceed to step 1:
The number 728 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 728

On to step 2:
If we divide 90 by 728, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Bring next digit (0) of the dividend behind the 90 and repeat the process: 900 / 728

On to step 3:
728 goes into 900 1 times with a remainder of 172.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 172 after subtracting 728 from 900.
Fetch the next digit (0) from the dividend, attach it to 172 and continue: 1720 / 728

Step 4:
When dividing 1720 by 728, we get 2 with a remainder of 264.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1456 from 1720 and we're left with 264.
Include the next digit (9) from the dividend after 264, then repeat: 2649 / 728

Let's proceed to step 5:
2649 divided by 728 is 3 with a remainder of 465.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtracting 2184 from 2649 leaves us with 465.
Bring next digit (2) of the dividend behind the 465 and repeat the process: 4652 / 728

Let's proceed to step 6:
728 can be fit into 4652 6 times, resulting in a remainder of 284.
Put 6 as the next digit of the answer. 
Result so far: 1236.0
If we subtract 4368 from 4652, we get 284.
Bring next digit (5) of the dividend behind the 284 and repeat the process: 2845 / 728

Moving on to step 7:
The number 728 fits into 2845 3 times, leaving a remainder of 661.
The next digit of our result is 3. 
Result so far: 12363.0
Subtract 2184 from 2845 to get 661.
Fetch the next digit (4) from the dividend, attach it to 661 and continue: 6614 / 728

Going ahead to step 8:
728 can be fit into 6614 9 times, resulting in a remainder of 62.
Write down 9 as next digit of the result. 
Result so far: 123639.0
The remainder is 62 after subtracting 6552 from 6614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
728 goes into 620 0 times with a remainder of 620.
The next digit of our result is 0. 
Result so far: 123639.0
Deduct 0 from 620 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 10:
728 goes into 6200 8 times with a remainder of 376.
Put 8 as the next digit of the answer. 
Result so far: 123639.08
Subtract 5824 from 6200 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 11:
728 can be fit into 3760 5 times, resulting in a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 123639.085
Subtracting 3640 from 3760 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
When dividing 1200 by 728, we get 1 with a remainder of 472.
Use 1 as the next digit of our solution. 
Result so far: 123639.0851
Subtracting 728 from 1200 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 13:
The number 728 fits into 4720 6 times, leaving a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 123639.08516
Subtracting 4368 from 4720 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 14:
When dividing 3520 by 728, we get 4 with a remainder of 608.
Use 4 as the next digit of our solution. 
Result so far: 123639.085164
If we take 2912 away from 3520, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 15:
If we divide 6080 by 728, we get 8 and a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 123639.0851648
The remainder is 256 after subtracting 5824 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 16:
The number 728 fits into 2560 3 times, leaving a remainder of 376.
Write down 3 as next digit of the result. 
Result so far: 123639.08516483
If we subtract 2184 from 2560, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final outcome is 123639.08516483, with a leftover of 3.76e-07.
