Let's divide 630998 by 23
The aim is to understand the frequency of 23 in 630998.

Step 1:
23 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 23

On to step 2:
23 goes into 63 2 times with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 46 from 63 and we're left with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 23

Moving on to step 3:
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: 27.0
If we take 161 away from 170, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 23

Advancing to step 4:
The number 23 fits into 99 4 times, leaving a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 274.0
Subtract 92 from 99 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 23

On to step 5:
23 can be fit into 79 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 2743.0
If we subtract 69 from 79, we get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 23

Let's proceed to step 6:
If we divide 108 by 23, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 27434.0
If we take 92 away from 108, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
23 goes into 160 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 27434.6
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 27434.69
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 9:
The number 23 fits into 130 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 27434.695
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 10:
23 can be fit into 150 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 27434.6956
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.

Step 11:
The number 23 fits into 120 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 27434.69565
Subtract 115 from 120 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 27434.695652
Subtract 46 from 50 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
When dividing 40 by 23, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 27434.6956521
Subtracting 23 from 40 leaves us 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 14:
When dividing 170 by 23, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 27434.69565217
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 27434.69565217, with a leftover of 9e-09.
