Let's divide 906104 by 23
The aim is to understand the frequency of 23 in 906104.

On to step 1:
When dividing 9 by 23, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 23

Let's proceed to step 2:
23 goes into 90 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 69 from 90 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 23

On to step 3:
The number 23 fits into 216 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtracting 207 from 216 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 23

Step 4:
91 divided by 23 is 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 393.0
The remainder is 22 after subtracting 69 from 91.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 23

Let's proceed to step 5:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 3939.0
If we take 207 away from 220, we end up with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 23

Step 6:
134 divided by 23 is 5 with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 39395.0
The remainder is 19 after subtracting 115 from 134.
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 7:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 39395.8
Subtracting 184 from 190 leaves us 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.

Let's proceed to step 8:
60 divided by 23 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 39395.82
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 39395.826
Subtracting 138 from 140 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
If we divide 20 by 23, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 39395.826
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
200 divided by 23 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 39395.82608
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On 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: 39395.826086
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.

Going ahead to step 13:
If we divide 220 by 23, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 39395.8260869
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
When dividing 130 by 23, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 39395.82608695
Subtract 115 from 130 to get 15.
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 39395.82608695, and the remainder is 1.5e-08.
