468238 divided by 91 
The aim is to understand the frequency of 91 in 468238.

On to step 1:
If we divide 4 by 91, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 91

On to step 2:
If we divide 46 by 91, we get 0 and a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 46, we get 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 91

Going ahead to step 3:
When dividing 468 by 91, we get 5 with a remainder of 13.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 455 from 468 to get 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 91

On to step 4:
132 divided by 91 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 91 from 132 and we're left with 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 91

Advancing to step 5:
91 can be fit into 413 4 times, resulting in a remainder of 49.
The next digit of our result is 4. 
Result so far: 514.0
Subtract 364 from 413 to get 49.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 91

Advancing to step 6:
When dividing 498 by 91, we get 5 with a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 5145.0
If we subtract 455 from 498, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
The number 91 fits into 430 4 times, leaving a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 5145.4
Deduct 364 from 430 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
If we divide 660 by 91, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 5145.47
Subtract 637 from 660 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
If we divide 230 by 91, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 5145.472
Subtracting 182 from 230 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
91 goes into 480 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 5145.4725
If we take 455 away from 480, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
250 divided by 91 is 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 5145.47252
Deduct 182 from 250 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
If we divide 680 by 91, we get 7 and a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 5145.472527
The remainder is 43 after subtracting 637 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 13:
When dividing 430 by 91, we get 4 with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 5145.4725274
Subtract 364 from 430 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 14:
91 goes into 660 7 times with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 5145.47252747
Subtracting 637 from 660 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 5145.47252747 with a balance of 2.3e-08.
