66049648 ÷ 414 
The aim is to understand the frequency of 414 in 66049648.

Step 1:
If we divide 6 by 414, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 414

Step 2:
66 divided by 414 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 414

Step 3:
414 goes into 660 1 times with a remainder of 246.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 246 after subtracting 414 from 660.
Fetch the next digit (4) from the dividend, attach it to 246 and continue: 2464 / 414

Going ahead to step 4:
If we divide 2464 by 414, we get 5 and a remainder of 394.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 2070 from 2464, we get 394.
Grab the next digit (9) from the dividend, add it to 394, then carry on: 3949 / 414

Going ahead to step 5:
When dividing 3949 by 414, we get 9 with a remainder of 223.
Put 9 as the next digit of the answer. 
Result so far: 159.0
The remainder is 223 after subtracting 3726 from 3949.
Bring next digit (6) of the dividend behind the 223 and repeat the process: 2236 / 414

Going ahead to step 6:
2236 divided by 414 is 5 with a remainder of 166.
Put 5 as the next digit of the answer. 
Result so far: 1595.0
Subtracting 2070 from 2236 leaves us with 166.
Grab the next digit (4) from the dividend, add it to 166, then carry on: 1664 / 414

Step 7:
414 can be fit into 1664 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 15954.0
Subtracting 1656 from 1664 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 414

Let's proceed to step 8:
88 divided by 414 is 0 with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 159540.0
Subtracting 0 from 88 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 9:
414 goes into 880 2 times with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 159540.2
Deduct 828 from 880 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
520 divided by 414 is 1 with a remainder of 106.
Write down 1 as next digit of the result. 
Result so far: 159540.21
If we take 414 away from 520, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 11:
1060 divided by 414 is 2 with a remainder of 232.
Write down 2 as next digit of the result. 
Result so far: 159540.212
If we take 828 away from 1060, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 12:
The number 414 fits into 2320 5 times, leaving a remainder of 250.
The next digit of our result is 5. 
Result so far: 159540.2125
The remainder is 250 after subtracting 2070 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
414 goes into 2500 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 159540.21256
Subtract 2484 from 2500 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
414 can be fit into 160 0 times, resulting in a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 159540.21256
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
When dividing 1600 by 414, we get 3 with a remainder of 358.
The next digit of our result is 3. 
Result so far: 159540.2125603
The remainder is 358 after subtracting 1242 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 16:
3580 divided by 414 is 8 with a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 159540.21256038
If we take 3312 away from 3580, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final result is 159540.21256038 with a remainder of 2.68e-07.
