646970 divided by 23 
Let's see how many times 23 fits into 646970.

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
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 23

Advancing to step 2:
If we divide 64 by 23, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 46 from 64, we get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 23

Moving on to step 3:
186 divided by 23 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 184 away from 186, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 23

Step 4:
23 goes into 29 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 281.0
Subtract 23 from 29 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 23

On to step 5:
23 goes into 67 2 times with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 2812.0
The remainder is 21 after subtracting 46 from 67.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 23

Moving on to step 6:
210 divided by 23 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 28129.0
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 7:
23 goes into 30 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 28129.1
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
If we divide 70 by 23, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 28129.13
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 9:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 28129.13
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.

On to step 10:
100 divided by 23 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 28129.1304
Deduct 92 from 100 and we're left 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 11:
When dividing 80 by 23, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 28129.13043
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.

Let's proceed to step 12:
The number 23 fits into 110 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 28129.130434
If we subtract 92 from 110, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
180 divided by 23 is 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 28129.1304347
If we take 161 away from 180, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 28129.13043478
Deduct 184 from 190 and we're left 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.

The quotient of the division is 28129.13043478, and the remainder is 6e-09.
