673731 divided by 23 
The aim is to understand the frequency of 23 in 673731.

Moving on to step 1:
23 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 23

Step 2:
The number 23 fits into 67 2 times, leaving a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 46 from 67, we get 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 23

Moving on to step 3:
When dividing 213 by 23, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 207 from 213 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 23

Step 4:
23 can be fit into 67 2 times, resulting in a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 292.0
If we subtract 46 from 67, we get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 23

On to step 5:
213 divided by 23 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 2929.0
Deduct 207 from 213 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 23

Advancing to step 6:
If we divide 61 by 23, we get 2 and a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 29292.0
The remainder is 15 after subtracting 46 from 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
150 divided by 23 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 29292.6
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
The number 23 fits into 120 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 29292.65
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.

Moving on to step 9:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 29292.652
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 10:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 29292.6521
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.

On to step 11:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 29292.65217
Subtracting 161 from 170 leaves us 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.

Advancing to step 12:
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: 29292.652173
Subtracting 69 from 90 leaves us 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.

Let's proceed to step 13:
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: 29292.6521739
Deduct 207 from 210 and we're left 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 14:
When dividing 30 by 23, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 29292.65217391
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.

The final outcome is 29292.65217391, with a leftover of 7e-09.
