We look at the division of 728431 by 23 
We want to divide 728431 by 23.

Advancing to step 1:
7 divided by 23 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 23

Moving on to step 2:
The number 23 fits into 72 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 69 from 72 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 23

Moving on to step 3:
38 divided by 23 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 23 from 38, we get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 23

Step 4:
The number 23 fits into 154 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 316.0
If we subtract 138 from 154, we get 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 23

Let's proceed to step 5:
163 divided by 23 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 3167.0
Subtracting 161 from 163 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 23

Moving on to step 6:
23 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 31670.0
If we take 0 away from 21, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
When dividing 210 by 23, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 31670.9
If we subtract 207 from 210, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
When dividing 30 by 23, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 31670.91
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
If we divide 70 by 23, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 31670.913
If we take 69 away from 70, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
If we divide 10 by 23, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 31670.913
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
When dividing 100 by 23, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 31670.91304
Deduct 92 from 100 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
The number 23 fits into 80 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 31670.913043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
The number 23 fits into 110 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 31670.9130434
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
180 divided by 23 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 31670.91304347
Subtracting 161 from 180 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 31670.91304347 with a remaining 1.9e-08.
