Let's divide 410723 by 91
The aim is to understand the frequency of 91 in 410723.

On to step 1:
4 divided by 91 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 91

Going ahead to step 2:
When dividing 41 by 91, we get 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 91

Let's proceed to step 3:
91 can be fit into 410 4 times, resulting in a remainder of 46.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 364 from 410 leaves us with 46.
Include the next digit (7) from the dividend after 46, then repeat: 467 / 91

Going ahead to step 4:
If we divide 467 by 91, we get 5 and a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we subtract 455 from 467, we get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 91

Step 5:
When dividing 122 by 91, we get 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 451.0
Subtracting 91 from 122 leaves us with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 91

On to step 6:
313 divided by 91 is 3 with a remainder of 40.
The next digit of our result is 3. 
Result so far: 4513.0
The remainder is 40 after subtracting 273 from 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
The number 91 fits into 400 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 4513.4
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
360 divided by 91 is 3 with a remainder of 87.
Write down 3 as next digit of the result. 
Result so far: 4513.43
The remainder is 87 after subtracting 273 from 360.
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 9:
91 can be fit into 870 9 times, resulting in a remainder of 51.
The next digit of our result is 9. 
Result so far: 4513.439
Deduct 819 from 870 and we're left 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.

Advancing to step 10:
91 goes into 510 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 4513.4395
Subtracting 455 from 510 leaves us 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.

Step 11:
When dividing 550 by 91, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 4513.43956
Deduct 546 from 550 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
If we divide 40 by 91, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4513.43956
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
400 divided by 91 is 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 4513.4395604
If we subtract 364 from 400, we 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.

Going ahead to step 14:
The number 91 fits into 360 3 times, leaving a remainder of 87.
The next digit of our result is 3. 
Result so far: 4513.43956043
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.

The final result is 4513.43956043 with a remainder of 8.7e-08.
