641500 divided by 23 
We want to figure out the number of times 641500 can be divided by 23.

Going ahead to step 1:
6 divided by 23 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 23

Moving on to step 2:
When dividing 64 by 23, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 46 from 64 and we're left with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 23

Advancing to step 3:
If we divide 181 by 23, we get 7 and a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtract 161 from 181 to get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 23

On to step 4:
205 divided by 23 is 8 with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 278.0
Subtracting 184 from 205 leaves us with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 23

Let's proceed to step 5:
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: 2789.0
The remainder is 3 after subtracting 207 from 210.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 23

Step 6:
When dividing 30 by 23, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 27891.0
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.

Moving on to step 7:
23 goes into 70 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 27891.3
If we subtract 69 from 70, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
The number 23 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 27891.3
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 27891.304
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
80 divided by 23 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 27891.3043
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
If we divide 110 by 23, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 27891.30434
If we take 92 away from 110, we end up 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.

Advancing to step 12:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 27891.304347
If we subtract 161 from 180, we get 19.
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 13:
23 goes into 190 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 27891.3043478
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.

Let's proceed to step 14:
23 can be fit into 60 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 27891.30434782
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 27891.30434782 with a remaining 1.4e-08.
