We're dividing 53765901 by 385 
The aim is to understand the frequency of 385 in 53765901.

Advancing to step 1:
5 divided by 385 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 385

Going ahead to step 2:
53 divided by 385 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 385

Advancing to step 3:
When dividing 537 by 385, we get 1 with a remainder of 152.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 385 away from 537, we end up with 152.
Bring next digit (6) of the dividend behind the 152 and repeat the process: 1526 / 385

Step 4:
1526 divided by 385 is 3 with a remainder of 371.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1155 from 1526, we get 371.
Include the next digit (5) from the dividend after 371, then repeat: 3715 / 385

On to step 5:
If we divide 3715 by 385, we get 9 and a remainder of 250.
Put 9 as the next digit of the answer. 
Result so far: 139.0
The remainder is 250 after subtracting 3465 from 3715.
Take the next digit (9) from the dividend and append it to 250, then repeat: 2509 / 385

Step 6:
2509 divided by 385 is 6 with a remainder of 199.
Put 6 as the next digit of the answer. 
Result so far: 1396.0
Deduct 2310 from 2509 and we're left with 199.
Grab the next digit (0) from the dividend, add it to 199, then carry on: 1990 / 385

Moving on to step 7:
When dividing 1990 by 385, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 13965.0
Subtracting 1925 from 1990 leaves us with 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 385

Advancing to step 8:
If we divide 651 by 385, we get 1 and a remainder of 266.
Use 1 as the next digit of our solution. 
Result so far: 139651.0
If we subtract 385 from 651, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 9:
The number 385 fits into 2660 6 times, leaving a remainder of 350.
Use 6 as the next digit of our solution. 
Result so far: 139651.6
If we subtract 2310 from 2660, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
The number 385 fits into 3500 9 times, leaving a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 139651.69
Subtract 3465 from 3500 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
When dividing 350 by 385, we get 0 with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 139651.69
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 12:
3500 divided by 385 is 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 139651.6909
Subtract 3465 from 3500 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
385 goes into 350 0 times with a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 139651.6909
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 14:
3500 divided by 385 is 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 139651.690909
If we take 3465 away from 3500, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 15:
385 goes into 350 0 times with a remainder of 350.
The next digit of our result is 0. 
Result so far: 139651.690909
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 16:
3500 divided by 385 is 9 with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 139651.69090909
Subtract 3465 from 3500 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 139651.69090909 and a remainder of 3.5e-08.
