We look at the division of 63393406 by 385 
The aim is to understand the frequency of 385 in 63393406.

Let's proceed to step 1:
6 divided by 385 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 385

Advancing to step 2:
If we divide 63 by 385, we get 0 and a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (3) of the dividend behind the 63 and repeat the process: 633 / 385

Step 3:
When dividing 633 by 385, we get 1 with a remainder of 248.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 385 from 633 to get 248.
Include the next digit (9) from the dividend after 248, then repeat: 2489 / 385

Let's proceed to step 4:
If we divide 2489 by 385, we get 6 and a remainder of 179.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 179 after subtracting 2310 from 2489.
Take the next digit (3) from the dividend and append it to 179, then repeat: 1793 / 385

Advancing to step 5:
The number 385 fits into 1793 4 times, leaving a remainder of 253.
Use 4 as the next digit of our solution. 
Result so far: 164.0
Deduct 1540 from 1793 and we're left with 253.
Fetch the next digit (4) from the dividend, attach it to 253 and continue: 2534 / 385

On to step 6:
385 can be fit into 2534 6 times, resulting in a remainder of 224.
Record the quotient 6 as the next digit in the result. 
Result so far: 1646.0
Subtract 2310 from 2534 to get 224.
Take the next digit (0) from the dividend and append it to 224, then repeat: 2240 / 385

Moving on to step 7:
385 goes into 2240 5 times with a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 16465.0
Deduct 1925 from 2240 and we're left with 315.
Include the next digit (6) from the dividend after 315, then repeat: 3156 / 385

Advancing to step 8:
385 can be fit into 3156 8 times, resulting in a remainder of 76.
The next digit of our result is 8. 
Result so far: 164658.0
The remainder is 76 after subtracting 3080 from 3156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
385 goes into 760 1 times with a remainder of 375.
Use 1 as the next digit of our solution. 
Result so far: 164658.1
If we take 385 away from 760, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 10:
If we divide 3750 by 385, we get 9 and a remainder of 285.
The next digit of our result is 9. 
Result so far: 164658.19
The remainder is 285 after subtracting 3465 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 11:
If we divide 2850 by 385, we get 7 and a remainder of 155.
The next digit of our result is 7. 
Result so far: 164658.197
Deduct 2695 from 2850 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 12:
385 can be fit into 1550 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 164658.1974
Subtracting 1540 from 1550 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
The number 385 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 164658.1974
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
1000 divided by 385 is 2 with a remainder of 230.
Write down 2 as next digit of the result. 
Result so far: 164658.197402
Deduct 770 from 1000 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 15:
385 can be fit into 2300 5 times, resulting in a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 164658.1974025
Subtract 1925 from 2300 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 16:
The number 385 fits into 3750 9 times, leaving a remainder of 285.
Write down 9 as next digit of the result. 
Result so far: 164658.19740259
If we subtract 3465 from 3750, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

The quotient of the division is 164658.19740259, and the remainder is 2.85e-07.
