We look at the division of 673580 by 23 
Let's see how many times 23 fits into 673580.

On to step 1:
23 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 23

Going ahead to step 2:
If we divide 67 by 23, we get 2 and a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 46 from 67, we get 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 23

Going ahead to step 3:
23 can be fit into 213 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 207 from 213 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 23

Moving on to step 4:
If we divide 65 by 23, we get 2 and a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 292.0
Subtracting 46 from 65 leaves us with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 23

Going ahead to step 5:
If we divide 198 by 23, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 2928.0
Subtract 184 from 198 to get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 23

Moving on to step 6:
If we divide 140 by 23, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 29286.0
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.

Advancing to step 7:
When dividing 20 by 23, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 29286.0
Deduct 0 from 20 and we're left with 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 8:
200 divided by 23 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 29286.08
If we subtract 184 from 200, we 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.

Step 9:
When dividing 160 by 23, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 29286.086
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 10:
If we divide 220 by 23, we get 9 and a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 29286.0869
Deduct 207 from 220 and we're left 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.

Let's proceed to step 11:
23 can be fit into 130 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 29286.08695
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
If we divide 150 by 23, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 29286.086956
If we take 138 away from 150, we end up 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.

Going ahead to step 13:
120 divided by 23 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 29286.0869565
Subtracting 115 from 120 leaves us 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 14:
23 goes into 50 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 29286.08695652
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.

The quotient of the division is 29286.08695652, and the remainder is 4e-09.
