We divide 12187423 by 728
We want to divide 12187423 by 728.

On to step 1:
If we divide 1 by 728, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 728

Moving on to step 2:
728 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 728

On to step 3:
The number 728 fits into 121 0 times, leaving a remainder of 121.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 121 after subtracting 0 from 121.
Bring next digit (8) of the dividend behind the 121 and repeat the process: 1218 / 728

Moving on to step 4:
If we divide 1218 by 728, we get 1 and a remainder of 490.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 728 away from 1218, we end up with 490.
Grab the next digit (7) from the dividend, add it to 490, then carry on: 4907 / 728

On to step 5:
4907 divided by 728 is 6 with a remainder of 539.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 4368 from 4907 to get 539.
Fetch the next digit (4) from the dividend, attach it to 539 and continue: 5394 / 728

Advancing to step 6:
When dividing 5394 by 728, we get 7 with a remainder of 298.
Use 7 as the next digit of our solution. 
Result so far: 167.0
The remainder is 298 after subtracting 5096 from 5394.
Include the next digit (2) from the dividend after 298, then repeat: 2982 / 728

Let's proceed to step 7:
728 goes into 2982 4 times with a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 1674.0
Subtracting 2912 from 2982 leaves us with 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 728

Going ahead to step 8:
728 can be fit into 703 0 times, resulting in a remainder of 703.
The number 0 becomes the next digit in our result. 
Result so far: 16740.0
Subtracting 0 from 703 leaves us with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Going ahead to step 9:
7030 divided by 728 is 9 with a remainder of 478.
Record the quotient 9 as the next digit in the result. 
Result so far: 16740.9
Subtracting 6552 from 7030 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Let's proceed to step 10:
728 goes into 4780 6 times with a remainder of 412.
The next digit of our result is 6. 
Result so far: 16740.96
Subtracting 4368 from 4780 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 11:
If we divide 4120 by 728, we get 5 and a remainder of 480.
Use 5 as the next digit of our solution. 
Result so far: 16740.965
The remainder is 480 after subtracting 3640 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
4800 divided by 728 is 6 with a remainder of 432.
Put 6 as the next digit of the answer. 
Result so far: 16740.9656
The remainder is 432 after subtracting 4368 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 13:
4320 divided by 728 is 5 with a remainder of 680.
The next digit of our result is 5. 
Result so far: 16740.96565
If we take 3640 away from 4320, we end up with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 14:
728 goes into 6800 9 times with a remainder of 248.
The next digit of our result is 9. 
Result so far: 16740.965659
If we take 6552 away from 6800, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 15:
728 goes into 2480 3 times with a remainder of 296.
Use 3 as the next digit of our solution. 
Result so far: 16740.9656593
Subtracting 2184 from 2480 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 16:
The number 728 fits into 2960 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 16740.96565934
If we subtract 2912 from 2960, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 16740.96565934, and the remainder is 4.8e-08.
