Let's divide 423946 by 23
Our goal is to divide 423946 by 23.

Going ahead to step 1:
If we divide 4 by 23, we get 0 and 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.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 23

On to step 2:
42 divided by 23 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 23 from 42 to get 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 23

Moving on to step 3:
193 divided by 23 is 8 with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 184 from 193 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 23

On to step 4:
The number 23 fits into 99 4 times, leaving a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 184.0
If we take 92 away from 99, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 23

Advancing to step 5:
23 goes into 74 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 1843.0
The remainder is 5 after subtracting 69 from 74.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 23

Going ahead to step 6:
56 divided by 23 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 18432.0
Subtracting 46 from 56 leaves us 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 7:
If we divide 100 by 23, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 18432.4
Subtract 92 from 100 to 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.

Going ahead to step 8:
If we divide 80 by 23, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 18432.43
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.

On to step 9:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 18432.434
If we take 92 away from 110, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
When dividing 180 by 23, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 18432.4347
Subtracting 161 from 180 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
If we divide 190 by 23, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 18432.43478
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.

Step 12:
60 divided by 23 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 18432.434782
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
If we divide 140 by 23, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 18432.4347826
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
23 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 18432.4347826
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 18432.4347826, with a leftover of 2e-08.
