Let's divide 426521 by 23
We want to divide 426521 by 23.

Step 1:
When dividing 4 by 23, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 23

Let's proceed to step 2:
When dividing 42 by 23, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 19 after subtracting 23 from 42.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 23

Moving on to step 3:
When dividing 196 by 23, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 12 after subtracting 184 from 196.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 23

Step 4:
If we divide 125 by 23, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 185.0
The remainder is 10 after subtracting 115 from 125.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 23

On to step 5:
23 goes into 102 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 1854.0
If we subtract 92 from 102, we get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 23

On to step 6:
23 goes into 101 4 times with a remainder of 9.
The next digit of our result is 4. 
Result so far: 18544.0
The remainder is 9 after subtracting 92 from 101.
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 7:
23 goes into 90 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 18544.3
The remainder is 21 after subtracting 69 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
23 goes into 210 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 18544.39
If we subtract 207 from 210, we 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.

Let's proceed to step 9:
23 goes into 30 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 18544.391
Subtracting 23 from 30 leaves us 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.

Let's proceed to step 10:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 18544.3913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
23 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 18544.3913
Subtracting 0 from 10 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.

Advancing to step 12:
When dividing 100 by 23, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 18544.391304
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.

On to step 13:
80 divided by 23 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 18544.3913043
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.

Step 14:
23 can be fit into 110 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 18544.39130434
Subtract 92 from 110 to 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.

The final outcome is 18544.39130434, with a leftover of 1.8e-08.
