We look at the division of 438492 by 23 
The aim is to understand the frequency of 23 in 438492.

Moving on to step 1:
If we divide 4 by 23, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 23

Moving on to step 2:
23 goes into 43 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 23 from 43 leaves us with 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 23

Let's proceed to step 3:
23 can be fit into 208 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 207 from 208 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 23

Let's proceed to step 4:
If we divide 14 by 23, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Subtract 0 from 14 to get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 23

On to step 5:
23 goes into 149 6 times with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 1906.0
The remainder is 11 after subtracting 138 from 149.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 23

Step 6:
112 divided by 23 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 19064.0
If we take 92 away from 112, 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.

Going ahead to step 7:
When dividing 200 by 23, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 19064.8
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.

Advancing to step 8:
160 divided by 23 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 19064.86
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
If we divide 220 by 23, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 19064.869
Subtract 207 from 220 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
When dividing 130 by 23, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 19064.8695
Deduct 115 from 130 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.

On to step 11:
When dividing 150 by 23, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 19064.86956
If we subtract 138 from 150, we 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.

Let's proceed to step 12:
If we divide 120 by 23, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 19064.869565
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
The number 23 fits into 50 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 19064.8695652
If we subtract 46 from 50, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
If we divide 40 by 23, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 19064.86956521
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.

The final result is 19064.86956521 with a remainder of 1.7e-08.
