We look at the division of 446143 by 23 
The aim is to understand the frequency of 23 in 446143.

Going ahead to step 1:
4 divided by 23 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 23

Step 2:
44 divided by 23 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 23 from 44 and we're left with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 23

On to step 3:
216 divided by 23 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 207 from 216, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 23

On to step 4:
If we divide 91 by 23, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 193.0
If we subtract 69 from 91, we get 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 23

On to step 5:
If we divide 224 by 23, we get 9 and a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 1939.0
If we take 207 away from 224, we end up with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 23

Going ahead to step 6:
If we divide 173 by 23, we get 7 and a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 19397.0
Subtract 161 from 173 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 7:
When dividing 120 by 23, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 19397.5
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.

Advancing to step 8:
50 divided by 23 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 19397.52
If we take 46 away from 50, we end up 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.

Let's proceed to step 9:
40 divided by 23 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 19397.521
The remainder is 17 after subtracting 23 from 40.
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 10:
When dividing 170 by 23, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 19397.5217
If we subtract 161 from 170, we 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.

Advancing to step 11:
If we divide 90 by 23, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 19397.52173
If we subtract 69 from 90, we 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.

Moving on to step 12:
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: 19397.521739
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.

Let's proceed to step 13:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 19397.5217391
Deduct 23 from 30 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 19397.52173913
Deduct 69 from 70 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 19397.52173913, with a leftover of 1e-09.
