We divide 666443 by 23
We want to figure out the number of times 666443 can be divided by 23.

Going ahead 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
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 23

Let's proceed to step 2:
The number 23 fits into 66 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 46 away from 66, we end up with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 23

Moving on to step 3:
23 goes into 206 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 28.0
The remainder is 22 after subtracting 184 from 206.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 23

Going ahead to step 4:
The number 23 fits into 224 9 times, leaving a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 289.0
Subtracting 207 from 224 leaves us with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 23

On to step 5:
The number 23 fits into 174 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 2897.0
If we take 161 away from 174, we end up with 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 23

Going ahead to step 6:
When dividing 133 by 23, we get 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 28975.0
Deduct 115 from 133 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
When dividing 180 by 23, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 28975.7
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
190 divided by 23 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 28975.78
Subtracting 184 from 190 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
23 can be fit into 60 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 28975.782
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
23 can be fit into 140 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 28975.7826
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 11:
23 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 28975.7826
If we subtract 0 from 20, we 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.

Moving on to step 12:
When dividing 200 by 23, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 28975.782608
If we take 184 away from 200, we end up 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.

Let's proceed to step 13:
23 can be fit into 160 6 times, resulting in a remainder of 22.
The next digit of our result is 6. 
Result so far: 28975.7826086
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.

Advancing to step 14:
The number 23 fits into 220 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 28975.78260869
If we take 207 away from 220, we end up 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.

The quotient of the division is 28975.78260869, and the remainder is 1.3e-08.
