Let's divide 65720545 by 385
The aim is to understand the frequency of 385 in 65720545.

Going ahead to step 1:
6 divided by 385 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 385

Let's proceed to step 2:
If we divide 65 by 385, we get 0 and a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 385

Advancing to step 3:
The number 385 fits into 657 1 times, leaving a remainder of 272.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 385 away from 657, we end up with 272.
Grab the next digit (2) from the dividend, add it to 272, then carry on: 2722 / 385

Going ahead to step 4:
385 goes into 2722 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 2695 from 2722, we get 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 385

On to step 5:
385 can be fit into 270 0 times, resulting in a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
Subtracting 0 from 270 leaves us with 270.
Bring next digit (5) of the dividend behind the 270 and repeat the process: 2705 / 385

Moving on to step 6:
The number 385 fits into 2705 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 1707.0
The remainder is 10 after subtracting 2695 from 2705.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 385

On to step 7:
The number 385 fits into 104 0 times, leaving a remainder of 104.
The next digit of our result is 0. 
Result so far: 17070.0
Subtracting 0 from 104 leaves us with 104.
Bring next digit (5) of the dividend behind the 104 and repeat the process: 1045 / 385

On to step 8:
385 goes into 1045 2 times with a remainder of 275.
The number 2 becomes the next digit in our result. 
Result so far: 170702.0
Subtract 770 from 1045 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 9:
385 can be fit into 2750 7 times, resulting in a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 170702.7
Subtract 2695 from 2750 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
When dividing 550 by 385, we get 1 with a remainder of 165.
The number 1 becomes the next digit in our result. 
Result so far: 170702.71
Subtract 385 from 550 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 11:
385 can be fit into 1650 4 times, resulting in a remainder of 110.
Put 4 as the next digit of the answer. 
Result so far: 170702.714
Subtracting 1540 from 1650 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 12:
385 goes into 1100 2 times with a remainder of 330.
Write down 2 as next digit of the result. 
Result so far: 170702.7142
Deduct 770 from 1100 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 13:
3300 divided by 385 is 8 with a remainder of 220.
Write down 8 as next digit of the result. 
Result so far: 170702.71428
Subtract 3080 from 3300 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 14:
When dividing 2200 by 385, we get 5 with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 170702.714285
The remainder is 275 after subtracting 1925 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 15:
2750 divided by 385 is 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 170702.7142857
If we subtract 2695 from 2750, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 16:
If we divide 550 by 385, we get 1 and a remainder of 165.
Use 1 as the next digit of our solution. 
Result so far: 170702.71428571
The remainder is 165 after subtracting 385 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final outcome is 170702.71428571, with a leftover of 1.65e-07.
