We look at the division of 23948051 by 305 
The aim is to understand the frequency of 305 in 23948051.

Going ahead to step 1:
305 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 305

Step 2:
If we divide 23 by 305, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 305

Let's proceed to step 3:
The number 305 fits into 239 0 times, leaving a remainder of 239.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 239 after subtracting 0 from 239.
Fetch the next digit (4) from the dividend, attach it to 239 and continue: 2394 / 305

On to step 4:
2394 divided by 305 is 7 with a remainder of 259.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 2135 away from 2394, we end up with 259.
Fetch the next digit (8) from the dividend, attach it to 259 and continue: 2598 / 305

Going ahead to step 5:
2598 divided by 305 is 8 with a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we subtract 2440 from 2598, we get 158.
Grab the next digit (0) from the dividend, add it to 158, then carry on: 1580 / 305

Advancing to step 6:
305 goes into 1580 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 785.0
If we subtract 1525 from 1580, we get 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 305

Let's proceed to step 7:
The number 305 fits into 555 1 times, leaving a remainder of 250.
Put 1 as the next digit of the answer. 
Result so far: 7851.0
Deduct 305 from 555 and we're left with 250.
Bring next digit (1) of the dividend behind the 250 and repeat the process: 2501 / 305

Advancing to step 8:
If we divide 2501 by 305, we get 8 and a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 78518.0
Deduct 2440 from 2501 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 9:
610 divided by 305 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 78518.2
Subtracting 610 from 610 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
305 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 78518.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
305 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 78518.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 78518.2 with a balance of 0.0.
