We look at the division of 87041709 by 414 
The aim is to understand the frequency of 414 in 87041709.

Step 1:
When dividing 8 by 414, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
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 / 414

Going ahead to step 2:
When dividing 87 by 414, we get 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 414

Step 3:
If we divide 870 by 414, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 42 after subtracting 828 from 870.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 414

Going ahead to step 4:
414 can be fit into 424 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 414 away from 424, we end up with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 414

Step 5:
414 can be fit into 101 0 times, resulting in a remainder of 101.
The next digit of our result is 0. 
Result so far: 210.0
The remainder is 101 after subtracting 0 from 101.
Include the next digit (7) from the dividend after 101, then repeat: 1017 / 414

On to step 6:
414 can be fit into 1017 2 times, resulting in a remainder of 189.
Put 2 as the next digit of the answer. 
Result so far: 2102.0
If we take 828 away from 1017, we end up with 189.
Include the next digit (0) from the dividend after 189, then repeat: 1890 / 414

On to step 7:
When dividing 1890 by 414, we get 4 with a remainder of 234.
Record the quotient 4 as the next digit in the result. 
Result so far: 21024.0
Subtracting 1656 from 1890 leaves us with 234.
Include the next digit (9) from the dividend after 234, then repeat: 2349 / 414

Let's proceed to step 8:
414 goes into 2349 5 times with a remainder of 279.
Write down 5 as next digit of the result. 
Result so far: 210245.0
Subtract 2070 from 2349 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 9:
The number 414 fits into 2790 6 times, leaving a remainder of 306.
Put 6 as the next digit of the answer. 
Result so far: 210245.6
If we take 2484 away from 2790, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 10:
If we divide 3060 by 414, we get 7 and a remainder of 162.
Put 7 as the next digit of the answer. 
Result so far: 210245.67
Deduct 2898 from 3060 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 11:
When dividing 1620 by 414, we get 3 with a remainder of 378.
Use 3 as the next digit of our solution. 
Result so far: 210245.673
Subtracting 1242 from 1620 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 12:
414 goes into 3780 9 times with a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 210245.6739
If we take 3726 away from 3780, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
The number 414 fits into 540 1 times, leaving a remainder of 126.
Put 1 as the next digit of the answer. 
Result so far: 210245.67391
The remainder is 126 after subtracting 414 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 14:
414 can be fit into 1260 3 times, resulting in a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 210245.673913
If we subtract 1242 from 1260, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 15:
180 divided by 414 is 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 210245.673913
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 16:
414 can be fit into 1800 4 times, resulting in a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 210245.67391304
If we take 1656 away from 1800, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Our division results in 210245.67391304 with a remaining 1.44e-07.
