Let's divide 14398205 by 91
The aim is to understand the frequency of 91 in 14398205.

Advancing to step 1:
91 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 91

Step 2:
The number 91 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 91

Advancing to step 3:
If we divide 143 by 91, we get 1 and a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 91 from 143 to get 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 91

On to step 4:
When dividing 529 by 91, we get 5 with a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 74 after subtracting 455 from 529.
Take the next digit (8) from the dividend and append it to 74, then repeat: 748 / 91

Step 5:
748 divided by 91 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 158.0
Deduct 728 from 748 and we're left with 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 91

Going ahead to step 6:
91 can be fit into 202 2 times, resulting in a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 1582.0
The remainder is 20 after subtracting 182 from 202.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 91

Let's proceed to step 7:
When dividing 200 by 91, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 15822.0
Subtracting 182 from 200 leaves us with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 91

Step 8:
When dividing 185 by 91, we get 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 158222.0
Deduct 182 from 185 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
30 divided by 91 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 158222.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
When dividing 300 by 91, we get 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 158222.03
The remainder is 27 after subtracting 273 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 11:
The number 91 fits into 270 2 times, leaving a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 158222.032
Subtract 182 from 270 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 12:
The number 91 fits into 880 9 times, leaving a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 158222.0329
Subtract 819 from 880 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 13:
91 can be fit into 610 6 times, resulting in a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 158222.03296
Subtracting 546 from 610 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
The number 91 fits into 640 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 158222.032967
Subtract 637 from 640 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 15:
91 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 158222.032967
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 16:
The number 91 fits into 300 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 158222.03296703
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 158222.03296703 with a balance of 2.7e-08.
