We look at the division of 836667 by 23 
The aim is to understand the frequency of 23 in 836667.

Let's proceed to step 1:
The number 23 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 23

Moving on to step 2:
83 divided by 23 is 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
If we take 69 away from 83, we end up with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 23

Going ahead to step 3:
23 can be fit into 146 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 8 after subtracting 138 from 146.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 23

Step 4:
86 divided by 23 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 363.0
Deduct 69 from 86 and we're left with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 23

On to step 5:
If we divide 176 by 23, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 3637.0
If we take 161 away from 176, we end up with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 23

Step 6:
If we divide 157 by 23, we get 6 and a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 36376.0
The remainder is 19 after subtracting 138 from 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
If we divide 190 by 23, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 36376.8
Deduct 184 from 190 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 23, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 36376.82
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
23 goes into 140 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 36376.826
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
23 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 36376.826
Deduct 0 from 20 and we're left 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.

Moving on to step 11:
If we divide 200 by 23, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 36376.82608
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 12:
The number 23 fits into 160 6 times, leaving a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 36376.826086
Subtract 138 from 160 to 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.

Let's proceed to step 13:
If we divide 220 by 23, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 36376.8260869
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.

Going ahead to step 14:
23 goes into 130 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 36376.82608695
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.

The quotient of the division is 36376.82608695, and the remainder is 1.5e-08.
