We divide 434451 by 23
We're looking to find how many times 23 goes into 434451.

Moving on to step 1:
23 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 23

On to step 2:
If we divide 43 by 23, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 23 from 43 and we're left with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 23

Going ahead to step 3:
When dividing 204 by 23, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 184 from 204, we get 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 23

Step 4:
23 goes into 204 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 188.0
The remainder is 20 after subtracting 184 from 204.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 23

Moving on to step 5:
23 goes into 205 8 times with a remainder of 21.
The next digit of our result is 8. 
Result so far: 1888.0
If we subtract 184 from 205, we get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 23

Going ahead to step 6:
If we divide 211 by 23, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 18889.0
Subtract 207 from 211 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
40 divided by 23 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 18889.1
Subtracting 23 from 40 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
When dividing 170 by 23, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 18889.17
Subtracting 161 from 170 leaves us 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 9:
When dividing 90 by 23, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 18889.173
If we subtract 69 from 90, we 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.

Going ahead to step 10:
When dividing 210 by 23, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 18889.1739
Subtracting 207 from 210 leaves us 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.

Let's proceed to step 11:
30 divided by 23 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 18889.17391
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.

Going ahead to step 12:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 18889.173913
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.

Advancing to step 13:
23 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 18889.173913
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 23, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 18889.17391304
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.

Our division results in 18889.17391304 with a remaining 8e-09.
