We look at the division of 461439 by 23 
The aim is to understand the frequency of 23 in 461439.

Let's proceed to step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 23

Advancing to step 2:
If we divide 46 by 23, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 46 from 46 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 23

Moving on to step 3:
23 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 1 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 23

Advancing to step 4:
If we divide 14 by 23, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 200.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 23

Step 5:
If we divide 143 by 23, we get 6 and a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 2006.0
Deduct 138 from 143 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 23

Advancing to step 6:
59 divided by 23 is 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 20062.0
Deduct 46 from 59 and we're left 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.

Going ahead to step 7:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 20062.5
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.

Step 8:
23 can be fit into 150 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 20062.56
Subtracting 138 from 150 leaves us 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.

On to step 9:
120 divided by 23 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 20062.565
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.

Going ahead to step 10:
If we divide 50 by 23, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 20062.5652
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.

Step 11:
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: 20062.56521
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.

Advancing to step 12:
23 can be fit into 170 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 20062.565217
The remainder is 9 after subtracting 161 from 170.
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 13:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 20062.5652173
If we take 69 away from 90, we end up 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.

Advancing to step 14:
210 divided by 23 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 20062.56521739
If we take 207 away from 210, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 20062.56521739 and a remainder of 3e-09.
