647721 ÷ 23 
Our goal is to divide 647721 by 23.

Let's proceed to step 1:
When dividing 6 by 23, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 23

Moving on to step 2:
23 goes into 64 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 46 from 64 and we're left with 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 23

Let's proceed to step 3:
187 divided by 23 is 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 184 from 187 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 23

Going ahead to step 4:
37 divided by 23 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 281.0
If we subtract 23 from 37, we get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 23

Moving on to step 5:
The number 23 fits into 142 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 2816.0
Deduct 138 from 142 and we're left with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 23

Going ahead to step 6:
The number 23 fits into 41 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 28161.0
The remainder is 18 after subtracting 23 from 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
23 goes into 180 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 28161.7
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.

Let's proceed to step 8:
When dividing 190 by 23, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 28161.78
If we subtract 184 from 190, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
23 goes into 60 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 28161.782
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
When dividing 140 by 23, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 28161.7826
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
20 divided by 23 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 28161.7826
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 28161.782608
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
If we divide 160 by 23, we get 6 and a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 28161.7826086
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 28161.78260869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 28161.78260869 with a remainder of 1.3e-08.
