479398 ÷ 23 
We're looking to find how many times 23 goes into 479398.

Going ahead to step 1:
4 divided by 23 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 23

Step 2:
If we divide 47 by 23, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 46 from 47 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 23

Going ahead to step 3:
19 divided by 23 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 19, we get 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 23

On to step 4:
When dividing 193 by 23, we get 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 208.0
If we subtract 184 from 193, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 23

Step 5:
The number 23 fits into 99 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 2084.0
Subtract 92 from 99 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 23

Advancing to step 6:
23 goes into 78 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 20843.0
If we take 69 away from 78, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 23 fits into 90 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 20843.3
The remainder is 21 after subtracting 69 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
If we divide 210 by 23, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 20843.39
If we take 207 away from 210, we end up 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.

Advancing to step 9:
30 divided by 23 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 20843.391
Deduct 23 from 30 and we're left 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.

Let's proceed to step 10:
If we divide 70 by 23, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 20843.3913
Subtracting 69 from 70 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
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: 20843.3913
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
The number 23 fits into 100 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 20843.391304
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.

Step 13:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 20843.3913043
The remainder is 11 after subtracting 69 from 80.
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 14:
110 divided by 23 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 20843.39130434
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.

After the division, we end up with 20843.39130434 and a remainder of 1.8e-08.
