We divide 689665 by 23
The aim is to understand the frequency of 23 in 689665.

Let's proceed to step 1:
When dividing 6 by 23, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 23

Going ahead to step 2:
When dividing 68 by 23, we get 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 46 away from 68, we end up with 22.
Take the next digit (9) from the dividend and append it to 22, then repeat: 229 / 23

Advancing to step 3:
229 divided by 23 is 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 29.0
Deduct 207 from 229 and we're left with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 23

Advancing to step 4:
When dividing 226 by 23, we get 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 299.0
Subtracting 207 from 226 leaves us with 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 23

Moving on to step 5:
If we divide 196 by 23, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 2998.0
Subtracting 184 from 196 leaves us with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 23

On to step 6:
If we divide 125 by 23, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 29985.0
Subtracting 115 from 125 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 23 fits into 100 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 29985.4
If we take 92 away from 100, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 29985.43
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 29985.434
If we subtract 92 from 110, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
If we divide 180 by 23, we get 7 and a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 29985.4347
Deduct 161 from 180 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 29985.43478
If we take 184 away from 190, we end up 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.

Moving on to step 12:
23 goes into 60 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 29985.434782
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
If we divide 140 by 23, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 29985.4347826
The remainder is 2 after subtracting 138 from 140.
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 14:
20 divided by 23 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 29985.4347826
If we take 0 away from 20, we end up 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.

The final result is 29985.4347826 with a remainder of 2e-08.
