We look at the division of 678561 by 23 
Let's see how many times 23 fits into 678561.

On to step 1:
23 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 23

Going ahead to step 2:
When dividing 67 by 23, we get 2 with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 46 from 67, we get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 23

Advancing to step 3:
When dividing 218 by 23, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 29.0
The remainder is 11 after subtracting 207 from 218.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 23

Going ahead to step 4:
23 can be fit into 115 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 295.0
Subtract 115 from 115 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 23

Moving on to step 5:
If we divide 6 by 23, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 2950.0
If we take 0 away from 6, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 23

Advancing to step 6:
The number 23 fits into 61 2 times, leaving a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 29502.0
The remainder is 15 after subtracting 46 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
If we divide 150 by 23, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 29502.6
If we subtract 138 from 150, we 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.

Step 8:
When dividing 120 by 23, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 29502.65
Deduct 115 from 120 and we're left with 5.
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 9:
50 divided by 23 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 29502.652
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 10:
23 goes into 40 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 29502.6521
Subtract 23 from 40 to 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.

Let's proceed to step 11:
23 goes into 170 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 29502.65217
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.

Moving on to step 12:
23 can be fit into 90 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 29502.652173
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.

On to step 13:
The number 23 fits into 210 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 29502.6521739
Deduct 207 from 210 and we're left 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.

Let's proceed to step 14:
23 goes into 30 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 29502.65217391
Subtracting 23 from 30 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 29502.65217391 and a remainder of 7e-09.
