We're dividing 87128095 by 415 
The aim is to understand the frequency of 415 in 87128095.

Going ahead to step 1:
If we divide 8 by 415, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 415

Moving on to step 2:
The number 415 fits into 87 0 times, leaving a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 415

Advancing to step 3:
The number 415 fits into 871 2 times, leaving a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 41 after subtracting 830 from 871.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 415

Going ahead to step 4:
The number 415 fits into 412 0 times, leaving a remainder of 412.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 412 leaves us with 412.
Append the next digit (8) from the dividend to 412 and continue with: 4128 / 415

Moving on to step 5:
415 can be fit into 4128 9 times, resulting in a remainder of 393.
Write down 9 as next digit of the result. 
Result so far: 209.0
The remainder is 393 after subtracting 3735 from 4128.
Append the next digit (0) from the dividend to 393 and continue with: 3930 / 415

On to step 6:
415 goes into 3930 9 times with a remainder of 195.
Write down 9 as next digit of the result. 
Result so far: 2099.0
If we take 3735 away from 3930, we end up with 195.
Take the next digit (9) from the dividend and append it to 195, then repeat: 1959 / 415

On to step 7:
If we divide 1959 by 415, we get 4 and a remainder of 299.
Use 4 as the next digit of our solution. 
Result so far: 20994.0
If we take 1660 away from 1959, we end up with 299.
Take the next digit (5) from the dividend and append it to 299, then repeat: 2995 / 415

Going ahead to step 8:
415 can be fit into 2995 7 times, resulting in a remainder of 90.
Write down 7 as next digit of the result. 
Result so far: 209947.0
The remainder is 90 after subtracting 2905 from 2995.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
415 can be fit into 900 2 times, resulting in a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 209947.2
Deduct 830 from 900 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
If we divide 700 by 415, we get 1 and a remainder of 285.
The next digit of our result is 1. 
Result so far: 209947.21
Subtracting 415 from 700 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 11:
2850 divided by 415 is 6 with a remainder of 360.
The number 6 becomes the next digit in our result. 
Result so far: 209947.216
Subtracting 2490 from 2850 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 12:
3600 divided by 415 is 8 with a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 209947.2168
The remainder is 280 after subtracting 3320 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 13:
When dividing 2800 by 415, we get 6 with a remainder of 310.
Put 6 as the next digit of the answer. 
Result so far: 209947.21686
Deduct 2490 from 2800 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 14:
415 can be fit into 3100 7 times, resulting in a remainder of 195.
Put 7 as the next digit of the answer. 
Result so far: 209947.216867
Subtract 2905 from 3100 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 15:
415 goes into 1950 4 times with a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 209947.2168674
Deduct 1660 from 1950 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 16:
415 goes into 2900 6 times with a remainder of 410.
Write down 6 as next digit of the result. 
Result so far: 209947.21686746
The remainder is 410 after subtracting 2490 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

After the division, we end up with 209947.21686746 and a remainder of 4.1e-07.
