We look at the division of 394079 by 23 
The aim is to understand the frequency of 23 in 394079.

Advancing to step 1:
When dividing 3 by 23, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 23

Let's proceed to step 2:
39 divided by 23 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 16 after subtracting 23 from 39.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 23

Let's proceed to step 3:
The number 23 fits into 164 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 161 from 164, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 23

Let's proceed to step 4:
23 goes into 30 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 171.0
If we take 23 away from 30, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 23

Going ahead to step 5:
23 can be fit into 77 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 1713.0
If we take 69 away from 77, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 23

Going ahead to step 6:
89 divided by 23 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 17133.0
Subtracting 69 from 89 leaves us 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.

On to step 7:
When dividing 200 by 23, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 17133.8
If we take 184 away from 200, we end up 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.

Let's proceed to step 8:
23 goes into 160 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 17133.86
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
If we divide 220 by 23, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 17133.869
Subtracting 207 from 220 leaves us with 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:
23 can be fit into 130 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 17133.8695
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.

Let's proceed to step 11:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 17133.86956
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 12:
120 divided by 23 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 17133.869565
If we subtract 115 from 120, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
When dividing 50 by 23, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 17133.8695652
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
23 goes into 40 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 17133.86956521
If we take 23 away from 40, we end up 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 quotient of the division is 17133.86956521, and the remainder is 1.7e-08.
