We look at the division of 631260 by 23 
The aim is to understand the frequency of 23 in 631260.

Going ahead to step 1:
If we divide 6 by 23, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 23

Step 2:
63 divided by 23 is 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 46 away from 63, we end up with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 23

Moving on to step 3:
The number 23 fits into 171 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 161 from 171 leaves us with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 23

Moving on to step 4:
The number 23 fits into 102 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 274.0
Subtract 92 from 102 to get 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 23

Let's proceed to step 5:
The number 23 fits into 106 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 2744.0
Deduct 92 from 106 and we're left with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 23

Advancing to step 6:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 27446.0
Subtract 138 from 140 to get 2.
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 7:
23 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 27446.0
Subtracting 0 from 20 leaves us 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.

Moving on to step 8:
23 can be fit into 200 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 27446.08
If we subtract 184 from 200, we 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.

Let's proceed to step 9:
If we divide 160 by 23, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 27446.086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
When dividing 220 by 23, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 27446.0869
Deduct 207 from 220 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
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: 27446.08695
If we take 115 away from 130, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
150 divided by 23 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 27446.086956
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.

Going ahead to step 13:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 27446.0869565
Deduct 115 from 120 and we're left 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.

Let's proceed to step 14:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 27446.08695652
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.

Our division results in 27446.08695652 with a remaining 4e-09.
