426431 divided by 23 
We want to figure out the number of times 426431 can be divided by 23.

Step 1:
23 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 23

Let's proceed to step 2:
If we divide 42 by 23, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 23 from 42 leaves us with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 23

Step 3:
If we divide 196 by 23, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 184 from 196 and we're left with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 23

Advancing to step 4:
124 divided by 23 is 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 185.0
If we subtract 115 from 124, we get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 23

Advancing to step 5:
23 goes into 93 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 1854.0
Subtract 92 from 93 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 23

Let's proceed to step 6:
The number 23 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 18540.0
If we subtract 0 from 11, 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.

Step 7:
The number 23 fits into 110 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 18540.4
Subtracting 92 from 110 leaves us 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.

On to step 8:
When dividing 180 by 23, we get 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 18540.47
Deduct 161 from 180 and we're left 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 9:
23 can be fit into 190 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 18540.478
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 10:
23 can be fit into 60 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 18540.4782
If we take 46 away from 60, we end up 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.

On to step 11:
If we divide 140 by 23, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 18540.47826
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.

Step 12:
20 divided by 23 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 18540.47826
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
23 goes into 200 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 18540.4782608
Subtracting 184 from 200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
If we divide 160 by 23, we get 6 and a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 18540.47826086
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 18540.47826086, and the remainder is 2.2e-08.
