179840 ÷ 23 
We want to divide 179840 by 23.

Step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 23

On to step 2:
The number 23 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 23

Moving on to step 3:
23 goes into 179 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 161 from 179, we get 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 23

Going ahead to step 4:
188 divided by 23 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtracting 184 from 188 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 23

Moving on to step 5:
If we divide 44 by 23, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 781.0
Deduct 23 from 44 and we're left with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 23

On to step 6:
23 can be fit into 210 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 7819.0
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 23 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 7819.1
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:
The number 23 fits into 70 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 7819.13
Subtract 69 from 70 to 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.

Step 9:
10 divided by 23 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7819.13
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 23, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 7819.1304
If we subtract 92 from 100, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
If we divide 80 by 23, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 7819.13043
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 12:
23 goes into 110 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 7819.130434
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
23 goes into 180 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 7819.1304347
Subtract 161 from 180 to 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.

Step 14:
23 goes into 190 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 7819.13043478
If we subtract 184 from 190, we get 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 final result is 7819.13043478 with a remainder of 6e-09.
