63871550 divided by 385 
The aim is to understand the frequency of 385 in 63871550.

Let's proceed to step 1:
When dividing 6 by 385, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 385

Moving on to step 2:
385 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 385

On to step 3:
When dividing 638 by 385, we get 1 with a remainder of 253.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 385 from 638 to get 253.
Take the next digit (7) from the dividend and append it to 253, then repeat: 2537 / 385

Step 4:
385 goes into 2537 6 times with a remainder of 227.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 2310 from 2537 leaves us with 227.
Take the next digit (1) from the dividend and append it to 227, then repeat: 2271 / 385

Going ahead to step 5:
When dividing 2271 by 385, we get 5 with a remainder of 346.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
Deduct 1925 from 2271 and we're left with 346.
Bring next digit (5) of the dividend behind the 346 and repeat the process: 3465 / 385

Step 6:
When dividing 3465 by 385, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 1659.0
Subtracting 3465 from 3465 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 385

On to step 7:
385 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 16590.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 385

On to step 8:
385 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 165900.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
If we divide 500 by 385, we get 1 and a remainder of 115.
The number 1 becomes the next digit in our result. 
Result so far: 165900.1
Subtract 385 from 500 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 10:
1150 divided by 385 is 2 with a remainder of 380.
The number 2 becomes the next digit in our result. 
Result so far: 165900.12
The remainder is 380 after subtracting 770 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 11:
385 can be fit into 3800 9 times, resulting in a remainder of 335.
Record the quotient 9 as the next digit in the result. 
Result so far: 165900.129
Subtract 3465 from 3800 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 12:
3350 divided by 385 is 8 with a remainder of 270.
Use 8 as the next digit of our solution. 
Result so far: 165900.1298
Subtract 3080 from 3350 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 13:
If we divide 2700 by 385, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 165900.12987
Subtracting 2695 from 2700 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
When dividing 50 by 385, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 165900.12987
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 15:
If we divide 500 by 385, we get 1 and a remainder of 115.
The number 1 becomes the next digit in our result. 
Result so far: 165900.1298701
Subtract 385 from 500 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 16:
If we divide 1150 by 385, we get 2 and a remainder of 380.
Write down 2 as next digit of the result. 
Result so far: 165900.12987012
If we subtract 770 from 1150, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

In conclusion, the division gives 165900.12987012 with a balance of 3.8e-07.
