184902 ÷ 91 
The aim is to understand the frequency of 91 in 184902.

Going ahead to step 1:
The number 91 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 91

Advancing to step 2:
18 divided by 91 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 91

Step 3:
If we divide 184 by 91, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 182 from 184 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 91

On to step 4:
29 divided by 91 is 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 29 to get 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 91

Step 5:
If we divide 290 by 91, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
The remainder is 17 after subtracting 273 from 290.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 91

Step 6:
172 divided by 91 is 1 with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 2031.0
Deduct 91 from 172 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 7:
810 divided by 91 is 8 with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 2031.8
If we take 728 away from 810, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 8:
If we divide 820 by 91, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 2031.89
Deduct 819 from 820 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
91 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2031.89
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
If we divide 100 by 91, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 2031.8901
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
When dividing 90 by 91, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 2031.8901
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 12:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 2031.890109
Subtracting 819 from 900 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 13:
91 goes into 810 8 times with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 2031.8901098
Subtracting 728 from 810 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 14:
91 can be fit into 820 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 2031.89010989
Subtract 819 from 820 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 2031.89010989 with a balance of 1e-09.
