We're dividing 648843 by 23 
We want to divide 648843 by 23.

Moving on to 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
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 23

Moving on to step 2:
64 divided by 23 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 46 from 64 and we're left with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 23

Going ahead to step 3:
188 divided by 23 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtracting 184 from 188 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 23

On to step 4:
48 divided by 23 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 282.0
If we take 46 away from 48, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 23

Step 5:
When dividing 24 by 23, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 2821.0
If we subtract 23 from 24, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 23

Going ahead to step 6:
When dividing 13 by 23, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 28210.0
If we subtract 0 from 13, 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.

Going ahead to step 7:
If we divide 130 by 23, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 28210.5
Subtracting 115 from 130 leaves us 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.

Step 8:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 28210.56
Subtracting 138 from 150 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 28210.565
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 28210.5652
If we subtract 46 from 50, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 28210.56521
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 28210.565217
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 28210.5652173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
210 divided by 23 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 28210.56521739
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 28210.56521739, with a leftover of 3e-09.
