708657 divided by 23 
The aim is to understand the frequency of 23 in 708657.

Step 1:
23 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 23

Step 2:
If we divide 70 by 23, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 69 from 70 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 23

Step 3:
23 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 23

Going ahead to step 4:
The number 23 fits into 186 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 308.0
Deduct 184 from 186 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 23

Let's proceed to step 5:
When dividing 25 by 23, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 3081.0
Subtract 23 from 25 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 23

Step 6:
23 can be fit into 27 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 30811.0
The remainder is 4 after subtracting 23 from 27.
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 7:
23 goes into 40 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 30811.1
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.

Let's proceed to step 8:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 30811.17
Deduct 161 from 170 and we're left 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.

On to step 9:
90 divided by 23 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 30811.173
Deduct 69 from 90 and we're left 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.

Step 10:
If we divide 210 by 23, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 30811.1739
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.

Moving on to step 11:
23 can be fit into 30 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 30811.17391
Subtract 23 from 30 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 30811.173913
If we take 69 away from 70, we end up 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.

Moving on to step 13:
The number 23 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 30811.173913
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
100 divided by 23 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 30811.17391304
Subtracting 92 from 100 leaves us 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.

The final outcome is 30811.17391304, with a leftover of 8e-09.
