We're dividing 393729 by 97 
The aim is to understand the frequency of 97 in 393729.

Advancing to step 1:
3 divided by 97 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 97

On to step 2:
39 divided by 97 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 97

On to step 3:
If we divide 393 by 97, we get 4 and a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 388 away from 393, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 97

Moving on to step 4:
The number 97 fits into 57 0 times, leaving a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 57 leaves us with 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 97

Moving on to step 5:
97 goes into 572 5 times with a remainder of 87.
The next digit of our result is 5. 
Result so far: 405.0
Subtract 485 from 572 to get 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 97

On to step 6:
97 goes into 879 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 4059.0
Deduct 873 from 879 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 97, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 4059.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
97 goes into 600 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 4059.06
Deduct 582 from 600 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
97 goes into 180 1 times with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 4059.061
The remainder is 83 after subtracting 97 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 10:
If we divide 830 by 97, we get 8 and a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 4059.0618
Subtract 776 from 830 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
The number 97 fits into 540 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 4059.06185
Deduct 485 from 540 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 12:
The number 97 fits into 550 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 4059.061855
If we take 485 away from 550, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 4059.061855 with a balance of 6.5e-06.
