We look at the division of 634838 by 23 
The aim is to understand the frequency of 23 in 634838.

Step 1:
When dividing 6 by 23, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 23

Step 2:
63 divided by 23 is 2 with a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 46 from 63, we get 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 23

Step 3:
23 goes into 174 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we subtract 161 from 174, we get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 23

Step 4:
The number 23 fits into 138 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 276.0
Subtracting 138 from 138 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 23

Moving on to step 5:
When dividing 3 by 23, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 2760.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 23

On to step 6:
The number 23 fits into 38 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 27601.0
Deduct 23 from 38 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
23 goes into 150 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 27601.6
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
23 goes into 120 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 27601.65
Deduct 115 from 120 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
23 goes into 50 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 27601.652
Deduct 46 from 50 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 27601.6521
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.

Let's proceed to step 11:
23 goes into 170 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 27601.65217
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
23 goes into 90 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 27601.652173
Subtract 69 from 90 to 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.

On to step 13:
When dividing 210 by 23, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 27601.6521739
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
23 goes into 30 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 27601.65217391
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.

After the division, we end up with 27601.65217391 and a remainder of 7e-09.
