We divide 425871 by 23
The aim is to understand the frequency of 23 in 425871.

Moving on to step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 23

Step 2:
23 can be fit into 42 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 23 from 42 to get 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 23

On to step 3:
The number 23 fits into 195 8 times, leaving a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 11 after subtracting 184 from 195.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 23

On to step 4:
23 can be fit into 118 5 times, resulting in a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
The remainder is 3 after subtracting 115 from 118.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 23

Advancing to step 5:
The number 23 fits into 37 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 1851.0
If we take 23 away from 37, we end up with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 23

On to step 6:
141 divided by 23 is 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 18516.0
Subtract 138 from 141 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.

Going ahead to step 7:
When dividing 30 by 23, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 18516.1
Subtract 23 from 30 to get 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 8:
23 can be fit into 70 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 18516.13
If we subtract 69 from 70, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
10 divided by 23 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 18516.13
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.

Let's proceed to step 10:
100 divided by 23 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 18516.1304
Subtracting 92 from 100 leaves us 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.

On to step 11:
23 can be fit into 80 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 18516.13043
If we take 69 away from 80, we end up with 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 12:
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: 18516.130434
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.

Going ahead to step 13:
23 can be fit into 180 7 times, resulting in a remainder of 19.
The next digit of our result is 7. 
Result so far: 18516.1304347
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.

Advancing to step 14:
23 goes into 190 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 18516.13043478
The remainder is 6 after subtracting 184 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 18516.13043478, and the remainder is 6e-09.
