23255670 divided by 399 
The aim is to understand the frequency of 399 in 23255670.

Moving on to step 1:
399 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 399

Let's proceed to step 2:
The number 399 fits into 23 0 times, leaving a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 399

Advancing to step 3:
If we divide 232 by 399, we get 0 and a remainder of 232.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 232 leaves us with 232.
Fetch the next digit (5) from the dividend, attach it to 232 and continue: 2325 / 399

Step 4:
If we divide 2325 by 399, we get 5 and a remainder of 330.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 1995 from 2325 and we're left with 330.
Bring next digit (5) of the dividend behind the 330 and repeat the process: 3305 / 399

On to step 5:
If we divide 3305 by 399, we get 8 and a remainder of 113.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Subtract 3192 from 3305 to get 113.
Take the next digit (6) from the dividend and append it to 113, then repeat: 1136 / 399

Advancing to step 6:
The number 399 fits into 1136 2 times, leaving a remainder of 338.
The next digit of our result is 2. 
Result so far: 582.0
Subtract 798 from 1136 to get 338.
Append the next digit (7) from the dividend to 338 and continue with: 3387 / 399

Going ahead to step 7:
When dividing 3387 by 399, we get 8 with a remainder of 195.
Use 8 as the next digit of our solution. 
Result so far: 5828.0
Subtracting 3192 from 3387 leaves us with 195.
Append the next digit (0) from the dividend to 195 and continue with: 1950 / 399

Going ahead to step 8:
If we divide 1950 by 399, we get 4 and a remainder of 354.
Record the quotient 4 as the next digit in the result. 
Result so far: 58284.0
Subtracting 1596 from 1950 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 9:
If we divide 3540 by 399, we get 8 and a remainder of 348.
The next digit of our result is 8. 
Result so far: 58284.8
If we take 3192 away from 3540, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 10:
399 can be fit into 3480 8 times, resulting in a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 58284.88
If we take 3192 away from 3480, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

In conclusion, the division gives 58284.88 with a balance of 0.288.
