We look at the division of 18330657 by 414 
The aim is to understand the frequency of 414 in 18330657.

On to step 1:
When dividing 1 by 414, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 414

Step 2:
When dividing 18 by 414, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 414

Moving on to step 3:
414 goes into 183 0 times with a remainder of 183.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 183 and we're left with 183.
Grab the next digit (3) from the dividend, add it to 183, then carry on: 1833 / 414

Advancing to step 4:
If we divide 1833 by 414, we get 4 and a remainder of 177.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 1656 from 1833 and we're left with 177.
Fetch the next digit (0) from the dividend, attach it to 177 and continue: 1770 / 414

Moving on to step 5:
If we divide 1770 by 414, we get 4 and a remainder of 114.
The next digit of our result is 4. 
Result so far: 44.0
If we take 1656 away from 1770, we end up with 114.
Grab the next digit (6) from the dividend, add it to 114, then carry on: 1146 / 414

Going ahead to step 6:
1146 divided by 414 is 2 with a remainder of 318.
The next digit of our result is 2. 
Result so far: 442.0
If we subtract 828 from 1146, we get 318.
Grab the next digit (5) from the dividend, add it to 318, then carry on: 3185 / 414

Let's proceed to step 7:
414 goes into 3185 7 times with a remainder of 287.
The number 7 becomes the next digit in our result. 
Result so far: 4427.0
Subtract 2898 from 3185 to get 287.
Take the next digit (7) from the dividend and append it to 287, then repeat: 2877 / 414

On to step 8:
414 can be fit into 2877 6 times, resulting in a remainder of 393.
The number 6 becomes the next digit in our result. 
Result so far: 44276.0
Subtracting 2484 from 2877 leaves us with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Advancing to step 9:
When dividing 3930 by 414, we get 9 with a remainder of 204.
The next digit of our result is 9. 
Result so far: 44276.9
Subtract 3726 from 3930 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 10:
414 can be fit into 2040 4 times, resulting in a remainder of 384.
Put 4 as the next digit of the answer. 
Result so far: 44276.94
The remainder is 384 after subtracting 1656 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 11:
414 goes into 3840 9 times with a remainder of 114.
The number 9 becomes the next digit in our result. 
Result so far: 44276.949
Subtract 3726 from 3840 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 12:
1140 divided by 414 is 2 with a remainder of 312.
Use 2 as the next digit of our solution. 
Result so far: 44276.9492
If we subtract 828 from 1140, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 13:
414 can be fit into 3120 7 times, resulting in a remainder of 222.
Put 7 as the next digit of the answer. 
Result so far: 44276.94927
If we subtract 2898 from 3120, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 14:
2220 divided by 414 is 5 with a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 44276.949275
Subtract 2070 from 2220 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 15:
414 can be fit into 1500 3 times, resulting in a remainder of 258.
The number 3 becomes the next digit in our result. 
Result so far: 44276.9492753
Subtract 1242 from 1500 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 16:
The number 414 fits into 2580 6 times, leaving a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 44276.94927536
The remainder is 96 after subtracting 2484 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final result is 44276.94927536 with a remainder of 9.6e-08.
