We look at the division of 479542 by 23 
We want to figure out the number of times 479542 can be divided by 23.

Advancing to step 1:
23 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 23

Step 2:
If we divide 47 by 23, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 46 from 47 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 23

On to step 3:
The number 23 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 23

Advancing to step 4:
23 goes into 195 8 times with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 208.0
The remainder is 11 after subtracting 184 from 195.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 23

Advancing to step 5:
23 goes into 114 4 times with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 2084.0
Subtracting 92 from 114 leaves us with 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 23

Let's proceed to step 6:
If we divide 222 by 23, we get 9 and a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 20849.0
The remainder is 15 after subtracting 207 from 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
150 divided by 23 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 20849.6
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
23 goes into 120 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 20849.65
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
If we divide 50 by 23, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 20849.652
Deduct 46 from 50 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
If we divide 40 by 23, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 20849.6521
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
170 divided by 23 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 20849.65217
Deduct 161 from 170 and we're left 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.

Advancing to step 12:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 20849.652173
Subtract 69 from 90 to get 21.
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 13:
210 divided by 23 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 20849.6521739
Subtract 207 from 210 to get 3.
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 14:
23 goes into 30 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 20849.65217391
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.

After the division, we end up with 20849.65217391 and a remainder of 7e-09.
