663148 ÷ 23 
We're looking to find how many times 23 goes into 663148.

Moving on to step 1:
If we divide 6 by 23, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 23

On to step 2:
The number 23 fits into 66 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 46 from 66, we get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 23

Moving on to step 3:
203 divided by 23 is 8 with a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 184 from 203 and we're left with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 23

Advancing to step 4:
23 goes into 191 8 times with a remainder of 7.
The next digit of our result is 8. 
Result so far: 288.0
The remainder is 7 after subtracting 184 from 191.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 23

Let's proceed to step 5:
The number 23 fits into 74 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 2883.0
Subtracting 69 from 74 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 23

Step 6:
When dividing 58 by 23, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 28832.0
The remainder is 12 after subtracting 46 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 23 fits into 120 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 28832.5
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.

Moving on to step 8:
23 goes into 50 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 28832.52
Deduct 46 from 50 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 23, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 28832.521
Subtracting 23 from 40 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
23 can be fit into 170 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 28832.5217
Deduct 161 from 170 and we're left with 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 11:
90 divided by 23 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 28832.52173
If we subtract 69 from 90, we 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.

Moving on to step 12:
If we divide 210 by 23, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 28832.521739
If we take 207 away from 210, we end up 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.

On to step 13:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 28832.5217391
If we take 23 away from 30, we end up 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.

Moving on to step 14:
70 divided by 23 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 28832.52173913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 28832.52173913, and the remainder is 1e-09.
