Let's divide 97548923 by 390
The aim is to understand the frequency of 390 in 97548923.

Moving on to step 1:
390 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 390

Step 2:
When dividing 97 by 390, we get 0 with a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Fetch the next digit (5) from the dividend, attach it to 97 and continue: 975 / 390

Advancing to step 3:
If we divide 975 by 390, we get 2 and a remainder of 195.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 780 from 975 and we're left with 195.
Grab the next digit (4) from the dividend, add it to 195, then carry on: 1954 / 390

Step 4:
The number 390 fits into 1954 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 1950 away from 1954, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 390

Moving on to step 5:
If we divide 48 by 390, we get 0 and a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
If we take 0 away from 48, we end up with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 390

Advancing to step 6:
390 goes into 489 1 times with a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 2501.0
Deduct 390 from 489 and we're left with 99.
Fetch the next digit (2) from the dividend, attach it to 99 and continue: 992 / 390

Going ahead to step 7:
If we divide 992 by 390, we get 2 and a remainder of 212.
Record the quotient 2 as the next digit in the result. 
Result so far: 25012.0
Deduct 780 from 992 and we're left with 212.
Append the next digit (3) from the dividend to 212 and continue with: 2123 / 390

Let's proceed to step 8:
390 can be fit into 2123 5 times, resulting in a remainder of 173.
Write down 5 as next digit of the result. 
Result so far: 250125.0
Subtract 1950 from 2123 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 9:
When dividing 1730 by 390, we get 4 with a remainder of 170.
Write down 4 as next digit of the result. 
Result so far: 250125.4
Subtract 1560 from 1730 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
The number 390 fits into 1700 4 times, leaving a remainder of 140.
The number 4 becomes the next digit in our result. 
Result so far: 250125.44
Subtracting 1560 from 1700 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

In conclusion, the division gives 250125.44 with a balance of 0.14.
