798640 ÷ 23 
Let's see how many times 23 fits into 798640.

Let's proceed to step 1:
7 divided by 23 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 23

On to step 2:
The number 23 fits into 79 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 10 after subtracting 69 from 79.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 23

On to step 3:
23 can be fit into 108 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 92 from 108 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 23

Advancing to step 4:
The number 23 fits into 166 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 347.0
Subtracting 161 from 166 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 23

On to step 5:
The number 23 fits into 54 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 3472.0
Subtract 46 from 54 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 23

Moving on to step 6:
When dividing 80 by 23, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 34723.0
Subtracting 69 from 80 leaves us 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 7:
110 divided by 23 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 34723.4
Deduct 92 from 110 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.

Step 8:
When dividing 180 by 23, we get 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 34723.47
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.

On to step 9:
If we divide 190 by 23, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 34723.478
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.

Step 10:
23 goes into 60 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 34723.4782
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
The number 23 fits into 140 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 34723.47826
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
The number 23 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 34723.47826
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.

Advancing to step 13:
23 goes into 200 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 34723.4782608
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.

On to step 14:
23 goes into 160 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 34723.47826086
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 34723.47826086 with a remainder of 2.2e-08.
