We're dividing 728399 by 48 
We want to figure out the number of times 728399 can be divided by 48.

Going ahead to step 1:
The number 48 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 48

On to step 2:
When dividing 72 by 48, we get 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 48 from 72 and we're left with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 48

On to step 3:
When dividing 248 by 48, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 240 from 248 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 48

On to step 4:
83 divided by 48 is 1 with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 151.0
If we subtract 48 from 83, we get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 48

Let's proceed to step 5:
48 can be fit into 359 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 1517.0
The remainder is 23 after subtracting 336 from 359.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 48

Moving on to step 6:
48 can be fit into 239 4 times, resulting in a remainder of 47.
The next digit of our result is 4. 
Result so far: 15174.0
If we subtract 192 from 239, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
470 divided by 48 is 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 15174.9
Deduct 432 from 470 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
The number 48 fits into 380 7 times, leaving a remainder of 44.
The next digit of our result is 7. 
Result so far: 15174.97
Subtract 336 from 380 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
48 goes into 440 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 15174.979
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
48 goes into 80 1 times with a remainder of 32.
The next digit of our result is 1. 
Result so far: 15174.9791
The remainder is 32 after subtracting 48 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
48 can be fit into 320 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 15174.97916
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
48 goes into 320 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 15174.979166
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 15174.979166, with a leftover of 3.2e-06.
