We divide 600396 by 23
The aim is to understand the frequency of 23 in 600396.

Step 1:
23 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 23

On to step 2:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 46 from 60 leaves us with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 23

Moving on to step 3:
23 can be fit into 140 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 2 after subtracting 138 from 140.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 23

Let's proceed to step 4:
If we divide 23 by 23, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 261.0
If we take 23 away from 23, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 23

On to step 5:
If we divide 9 by 23, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 2610.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 23

Going ahead to step 6:
The number 23 fits into 96 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 26104.0
Deduct 92 from 96 and we're left 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.

Going ahead to step 7:
When dividing 40 by 23, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 26104.1
Subtract 23 from 40 to 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.

Step 8:
If we divide 170 by 23, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 26104.17
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.

Advancing to step 9:
If we divide 90 by 23, we get 3 and a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 26104.173
Subtract 69 from 90 to 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.

Advancing to step 10:
23 goes into 210 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 26104.1739
Subtracting 207 from 210 leaves us 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.

On to step 11:
If we divide 30 by 23, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 26104.17391
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 26104.173913
Subtract 69 from 70 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
23 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 26104.173913
Deduct 0 from 10 and we're left 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.

On to step 14:
23 can be fit into 100 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 26104.17391304
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 quotient of the division is 26104.17391304, and the remainder is 8e-09.
