We're dividing 407305 by 23 
Our goal is to divide 407305 by 23.

Step 1:
23 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 23

Step 2:
23 can be fit into 40 1 times, resulting in a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 23 from 40 leaves us with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 23

On to step 3:
When dividing 177 by 23, we get 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 161 from 177, we get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 23

Going ahead to step 4:
23 can be fit into 163 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
Subtracting 161 from 163 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 23

On to step 5:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1770.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 23

Let's proceed to step 6:
23 goes into 205 8 times with a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 17708.0
The remainder is 21 after subtracting 184 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
23 goes into 210 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 17708.9
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 8:
30 divided by 23 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 17708.91
If we take 23 away from 30, we end up 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.

Moving on to step 9:
70 divided by 23 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 17708.913
Deduct 69 from 70 and we're left 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 10:
When dividing 10 by 23, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 17708.913
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 11:
When dividing 100 by 23, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 17708.91304
If we take 92 away from 100, we end up 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.

Going ahead to step 12:
80 divided by 23 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 17708.913043
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
When dividing 110 by 23, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 17708.9130434
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.

Moving on to step 14:
If we divide 180 by 23, we get 7 and a remainder of 19.
The next digit of our result is 7. 
Result so far: 17708.91304347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 17708.91304347, with a leftover of 1.9e-08.
