Let's divide 91025279 by 414
The aim is to understand the frequency of 414 in 91025279.

On to step 1:
If we divide 9 by 414, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 414

Advancing to step 2:
The number 414 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 414

Moving on to step 3:
When dividing 910 by 414, we get 2 with a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 828 away from 910, we end up with 82.
Bring next digit (2) of the dividend behind the 82 and repeat the process: 822 / 414

Moving on to step 4:
If we divide 822 by 414, we get 1 and a remainder of 408.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 414 from 822 and we're left with 408.
Append the next digit (5) from the dividend to 408 and continue with: 4085 / 414

Going ahead to step 5:
When dividing 4085 by 414, we get 9 with a remainder of 359.
Put 9 as the next digit of the answer. 
Result so far: 219.0
Subtracting 3726 from 4085 leaves us with 359.
Include the next digit (2) from the dividend after 359, then repeat: 3592 / 414

Step 6:
3592 divided by 414 is 8 with a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 2198.0
Subtracting 3312 from 3592 leaves us with 280.
Take the next digit (7) from the dividend and append it to 280, then repeat: 2807 / 414

Advancing to step 7:
When dividing 2807 by 414, we get 6 with a remainder of 323.
Record the quotient 6 as the next digit in the result. 
Result so far: 21986.0
The remainder is 323 after subtracting 2484 from 2807.
Include the next digit (9) from the dividend after 323, then repeat: 3239 / 414

Advancing to step 8:
If we divide 3239 by 414, we get 7 and a remainder of 341.
Put 7 as the next digit of the answer. 
Result so far: 219867.0
If we subtract 2898 from 3239, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 9:
If we divide 3410 by 414, we get 8 and a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 219867.8
Subtract 3312 from 3410 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 10:
414 can be fit into 980 2 times, resulting in a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 219867.82
The remainder is 152 after subtracting 828 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 11:
The number 414 fits into 1520 3 times, leaving a remainder of 278.
The number 3 becomes the next digit in our result. 
Result so far: 219867.823
If we subtract 1242 from 1520, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 12:
The number 414 fits into 2780 6 times, leaving a remainder of 296.
Put 6 as the next digit of the answer. 
Result so far: 219867.8236
If we subtract 2484 from 2780, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 13:
The number 414 fits into 2960 7 times, leaving a remainder of 62.
The next digit of our result is 7. 
Result so far: 219867.82367
The remainder is 62 after subtracting 2898 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 14:
When dividing 620 by 414, we get 1 with a remainder of 206.
Record the quotient 1 as the next digit in the result. 
Result so far: 219867.823671
Subtracting 414 from 620 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 15:
The number 414 fits into 2060 4 times, leaving a remainder of 404.
Use 4 as the next digit of our solution. 
Result so far: 219867.8236714
Subtract 1656 from 2060 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 16:
When dividing 4040 by 414, we get 9 with a remainder of 314.
The next digit of our result is 9. 
Result so far: 219867.82367149
Subtract 3726 from 4040 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

The final result is 219867.82367149 with a remainder of 3.14e-07.
