Let's divide 121800 by 23
The aim is to understand the frequency of 23 in 121800.

Let's proceed to step 1:
The number 23 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 23

Step 2:
If we divide 12 by 23, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 23

Moving on to step 3:
If we divide 121 by 23, we get 5 and a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
If we take 115 away from 121, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 23

Step 4:
23 goes into 68 2 times with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtracting 46 from 68 leaves us with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 23

Advancing to step 5:
When dividing 220 by 23, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 529.0
If we take 207 away from 220, we end up with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 23

On to step 6:
130 divided by 23 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 5295.0
Subtracting 115 from 130 leaves us 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 7:
23 can be fit into 150 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 5295.6
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5295.65
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.

Going ahead to step 9:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 5295.652
If we take 46 away from 50, we end up 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 10:
If we divide 40 by 23, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 5295.6521
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.

Moving on to step 11:
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: 5295.65217
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.

On to step 12:
When dividing 90 by 23, we get 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 5295.652173
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.

Let's proceed to step 13:
210 divided by 23 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 5295.6521739
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
When dividing 30 by 23, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 5295.65217391
If we subtract 23 from 30, we 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.

In conclusion, the division gives 5295.65217391 with a balance of 7e-09.
