We divide 3454431 by 728
We're looking to find how many times 728 goes into 3454431.

On to step 1:
If we divide 3 by 728, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 728

Moving on to step 2:
The number 728 fits into 34 0 times, leaving a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 728

On to step 3:
728 goes into 345 0 times with a remainder of 345.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 345, we get 345.
Include the next digit (4) from the dividend after 345, then repeat: 3454 / 728

Advancing to step 4:
When dividing 3454 by 728, we get 4 with a remainder of 542.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 2912 from 3454 leaves us with 542.
Append the next digit (4) from the dividend to 542 and continue with: 5424 / 728

Moving on to step 5:
728 can be fit into 5424 7 times, resulting in a remainder of 328.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtracting 5096 from 5424 leaves us with 328.
Take the next digit (3) from the dividend and append it to 328, then repeat: 3283 / 728

On to step 6:
The number 728 fits into 3283 4 times, leaving a remainder of 371.
Write down 4 as next digit of the result. 
Result so far: 474.0
If we take 2912 away from 3283, we end up with 371.
Append the next digit (1) from the dividend to 371 and continue with: 3711 / 728

Step 7:
728 goes into 3711 5 times with a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 4745.0
The remainder is 71 after subtracting 3640 from 3711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 8:
When dividing 710 by 728, we get 0 with a remainder of 710.
The next digit of our result is 0. 
Result so far: 4745.0
If we subtract 0 from 710, we get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Let's proceed to step 9:
When dividing 7100 by 728, we get 9 with a remainder of 548.
Put 9 as the next digit of the answer. 
Result so far: 4745.09
Subtract 6552 from 7100 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 10:
728 goes into 5480 7 times with a remainder of 384.
Use 7 as the next digit of our solution. 
Result so far: 4745.097
The remainder is 384 after subtracting 5096 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 11:
The number 728 fits into 3840 5 times, leaving a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 4745.0975
Subtracting 3640 from 3840 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
728 can be fit into 2000 2 times, resulting in a remainder of 544.
The next digit of our result is 2. 
Result so far: 4745.09752
Subtracting 1456 from 2000 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 13:
When dividing 5440 by 728, we get 7 with a remainder of 344.
Record the quotient 7 as the next digit in the result. 
Result so far: 4745.097527
The remainder is 344 after subtracting 5096 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 14:
728 can be fit into 3440 4 times, resulting in a remainder of 528.
Put 4 as the next digit of the answer. 
Result so far: 4745.0975274
Subtracting 2912 from 3440 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 15:
If we divide 5280 by 728, we get 7 and a remainder of 184.
Record the quotient 7 as the next digit in the result. 
Result so far: 4745.09752747
Subtracting 5096 from 5280 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

After the division, we end up with 4745.09752747 and a remainder of 1.84e-07.
