We're dividing 379200 by 23 
The aim is to understand the frequency of 23 in 379200.

Moving on to step 1:
If we divide 3 by 23, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 23

Let's proceed to step 2:
37 divided by 23 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 14 after subtracting 23 from 37.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 23

Moving on to step 3:
149 divided by 23 is 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 138 away from 149, we end up with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 23

Advancing to step 4:
112 divided by 23 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
If we take 92 away from 112, we end up with 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 23

Let's proceed to step 5:
The number 23 fits into 200 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 1648.0
If we take 184 away from 200, we end up with 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 23

Moving on to step 6:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 16486.0
If we take 138 away from 160, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
23 goes into 220 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 16486.9
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.

Going ahead to step 8:
If we divide 130 by 23, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 16486.95
The remainder is 15 after subtracting 115 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
23 can be fit into 150 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 16486.956
Deduct 138 from 150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 16486.9565
Subtracting 115 from 120 leaves us 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 11:
50 divided by 23 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 16486.95652
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.

Step 12:
23 can be fit into 40 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 16486.956521
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 13:
170 divided by 23 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 16486.9565217
Deduct 161 from 170 and we're left with 9.
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 14:
When dividing 90 by 23, we get 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 16486.95652173
Deduct 69 from 90 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 16486.95652173, with a leftover of 2.1e-08.
