648131 ÷ 23 
Let's see how many times 23 fits into 648131.

Step 1:
6 divided by 23 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 23

Advancing to step 2:
23 can be fit into 64 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
If we take 46 away from 64, we end up with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 23

Advancing to step 3:
23 can be fit into 188 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 4 after subtracting 184 from 188.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 23

Let's proceed to step 4:
When dividing 41 by 23, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 281.0
Deduct 23 from 41 and we're left with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 23

Let's proceed to step 5:
If we divide 183 by 23, we get 7 and a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 2817.0
Subtracting 161 from 183 leaves us with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 23

Advancing to step 6:
221 divided by 23 is 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 28179.0
Subtracting 207 from 221 leaves us 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.

On to step 7:
23 can be fit into 140 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 28179.6
If we subtract 138 from 140, we get 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 8:
The number 23 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 28179.6
Subtract 0 from 20 to 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.

On to step 9:
23 can be fit into 200 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 28179.608
Deduct 184 from 200 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
23 can be fit into 160 6 times, resulting in a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 28179.6086
The remainder is 22 after subtracting 138 from 160.
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 11:
23 goes into 220 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 28179.60869
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
If we divide 130 by 23, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 28179.608695
If we take 115 away from 130, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
23 can be fit into 150 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 28179.6086956
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
When dividing 120 by 23, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 28179.60869565
Subtract 115 from 120 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 28179.60869565 and a remainder of 5e-09.
