417001 divided by 91 
The aim is to understand the frequency of 91 in 417001.

Let's proceed to step 1:
91 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 91

Step 2:
91 goes into 41 0 times with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 91

Advancing to step 3:
If we divide 417 by 91, we get 4 and a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 364 from 417 and we're left with 53.
Include the next digit (0) from the dividend after 53, then repeat: 530 / 91

Let's proceed to step 4:
The number 91 fits into 530 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 455 away from 530, we end up with 75.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 91

Going ahead to step 5:
91 can be fit into 750 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 458.0
Subtract 728 from 750 to get 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 91

Advancing to step 6:
91 goes into 221 2 times with a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 4582.0
Subtract 182 from 221 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
If we divide 390 by 91, we get 4 and a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 4582.4
Deduct 364 from 390 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
If we divide 260 by 91, we get 2 and a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 4582.42
If we take 182 away from 260, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
91 can be fit into 780 8 times, resulting in a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 4582.428
Subtract 728 from 780 to get 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:
If we divide 520 by 91, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 4582.4285
If we take 455 away from 520, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
When dividing 650 by 91, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 4582.42857
If we take 637 away from 650, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
If we divide 130 by 91, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 4582.428571
Deduct 91 from 130 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
If we divide 390 by 91, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 4582.4285714
Subtracting 364 from 390 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
260 divided by 91 is 2 with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 4582.42857142
Subtract 182 from 260 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 4582.42857142 with a balance of 7.8e-08.
