We're dividing 24312309 by 154 
The aim is to understand the frequency of 154 in 24312309.

Step 1:
If we divide 2 by 154, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 154

Going ahead to step 2:
24 divided by 154 is 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 154

Moving on to step 3:
The number 154 fits into 243 1 times, leaving a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 154 from 243, we get 89.
Fetch the next digit (1) from the dividend, attach it to 89 and continue: 891 / 154

Let's proceed to step 4:
The number 154 fits into 891 5 times, leaving a remainder of 121.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 770 from 891 and we're left with 121.
Append the next digit (2) from the dividend to 121 and continue with: 1212 / 154

Let's proceed to step 5:
154 can be fit into 1212 7 times, resulting in a remainder of 134.
Use 7 as the next digit of our solution. 
Result so far: 157.0
Subtracting 1078 from 1212 leaves us with 134.
Append the next digit (3) from the dividend to 134 and continue with: 1343 / 154

Moving on to step 6:
If we divide 1343 by 154, we get 8 and a remainder of 111.
Use 8 as the next digit of our solution. 
Result so far: 1578.0
If we take 1232 away from 1343, we end up with 111.
Bring next digit (0) of the dividend behind the 111 and repeat the process: 1110 / 154

On to step 7:
154 goes into 1110 7 times with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 15787.0
If we take 1078 away from 1110, we end up with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 154

Step 8:
If we divide 329 by 154, we get 2 and a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 157872.0
Subtracting 308 from 329 leaves us with 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 9:
210 divided by 154 is 1 with a remainder of 56.
The next digit of our result is 1. 
Result so far: 157872.1
Subtracting 154 from 210 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
When dividing 560 by 154, we get 3 with a remainder of 98.
Use 3 as the next digit of our solution. 
Result so far: 157872.13
Subtract 462 from 560 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 11:
The number 154 fits into 980 6 times, leaving a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 157872.136
Deduct 924 from 980 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
When dividing 560 by 154, we get 3 with a remainder of 98.
The next digit of our result is 3. 
Result so far: 157872.1363
The remainder is 98 after subtracting 462 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 13:
980 divided by 154 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 157872.13636
Deduct 924 from 980 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
If we divide 560 by 154, we get 3 and a remainder of 98.
The next digit of our result is 3. 
Result so far: 157872.136363
If we subtract 462 from 560, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 15:
154 can be fit into 980 6 times, resulting in a remainder of 56.
The next digit of our result is 6. 
Result so far: 157872.1363636
If we subtract 924 from 980, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 16:
The number 154 fits into 560 3 times, leaving a remainder of 98.
The next digit of our result is 3. 
Result so far: 157872.13636363
The remainder is 98 after subtracting 462 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

In conclusion, the division gives 157872.13636363 with a balance of 9.8e-08.
