410446 ÷ 91 
The aim is to understand the frequency of 91 in 410446.

Going ahead to step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 91

Advancing to step 2:
If we divide 41 by 91, we get 0 and a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 91

Moving on to step 3:
410 divided by 91 is 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 364 from 410, we get 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 91

Let's proceed to step 4:
464 divided by 91 is 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 9 after subtracting 455 from 464.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 91

Step 5:
91 goes into 94 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 451.0
The remainder is 3 after subtracting 91 from 94.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 91

On to step 6:
91 goes into 36 0 times with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 4510.0
The remainder is 36 after subtracting 0 from 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 91 fits into 360 3 times, leaving a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 4510.3
Subtracting 273 from 360 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 8:
The number 91 fits into 870 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 4510.39
If we take 819 away from 870, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
91 can be fit into 510 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 4510.395
If we take 455 away from 510, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
If we divide 550 by 91, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 4510.3956
The remainder is 4 after subtracting 546 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
91 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4510.3956
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
91 goes into 400 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 4510.395604
Subtract 364 from 400 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
The number 91 fits into 360 3 times, leaving a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 4510.3956043
Subtracting 273 from 360 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 14:
When dividing 870 by 91, we get 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 4510.39560439
If we take 819 away from 870, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final outcome is 4510.39560439, with a leftover of 5.1e-08.
