38987355 divided by 415 
The aim is to understand the frequency of 415 in 38987355.

On to step 1:
The number 415 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 415

On to step 2:
415 goes into 38 0 times with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 415

Let's proceed to step 3:
389 divided by 415 is 0 with a remainder of 389.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 389 after subtracting 0 from 389.
Grab the next digit (8) from the dividend, add it to 389, then carry on: 3898 / 415

Step 4:
When dividing 3898 by 415, we get 9 with a remainder of 163.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 3735 away from 3898, we end up with 163.
Bring next digit (7) of the dividend behind the 163 and repeat the process: 1637 / 415

Step 5:
If we divide 1637 by 415, we get 3 and a remainder of 392.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we take 1245 away from 1637, we end up with 392.
Include the next digit (3) from the dividend after 392, then repeat: 3923 / 415

Step 6:
The number 415 fits into 3923 9 times, leaving a remainder of 188.
Put 9 as the next digit of the answer. 
Result so far: 939.0
Deduct 3735 from 3923 and we're left with 188.
Append the next digit (5) from the dividend to 188 and continue with: 1885 / 415

Let's proceed to step 7:
If we divide 1885 by 415, we get 4 and a remainder of 225.
The number 4 becomes the next digit in our result. 
Result so far: 9394.0
If we take 1660 away from 1885, we end up with 225.
Grab the next digit (5) from the dividend, add it to 225, then carry on: 2255 / 415

Moving on to step 8:
415 can be fit into 2255 5 times, resulting in a remainder of 180.
The number 5 becomes the next digit in our result. 
Result so far: 93945.0
The remainder is 180 after subtracting 2075 from 2255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 9:
The number 415 fits into 1800 4 times, leaving a remainder of 140.
The next digit of our result is 4. 
Result so far: 93945.4
If we take 1660 away from 1800, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
When dividing 1400 by 415, we get 3 with a remainder of 155.
The number 3 becomes the next digit in our result. 
Result so far: 93945.43
If we subtract 1245 from 1400, we get 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 11:
When dividing 1550 by 415, we get 3 with a remainder of 305.
The number 3 becomes the next digit in our result. 
Result so far: 93945.433
Deduct 1245 from 1550 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

In conclusion, the division gives 93945.433 with a balance of 0.0305.
