We're dividing 730202 by 91 
The aim is to understand the frequency of 91 in 730202.

Let's proceed to step 1:
91 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 91

On to step 2:
The number 91 fits into 73 0 times, leaving a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 91

Let's proceed to step 3:
91 goes into 730 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 728 away from 730, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 91

Let's proceed to step 4:
The number 91 fits into 22 0 times, leaving a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Deduct 0 from 22 and we're left with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 91

Advancing to step 5:
220 divided by 91 is 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 802.0
Deduct 182 from 220 and we're left with 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 91

Step 6:
382 divided by 91 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 8024.0
Subtract 364 from 382 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
The number 91 fits into 180 1 times, leaving a remainder of 89.
The next digit of our result is 1. 
Result so far: 8024.1
If we subtract 91 from 180, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 8:
890 divided by 91 is 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 8024.19
If we take 819 away from 890, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
91 goes into 710 7 times with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 8024.197
The remainder is 73 after subtracting 637 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 10:
When dividing 730 by 91, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8024.1978
Subtracting 728 from 730 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
If we divide 20 by 91, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8024.1978
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
If we divide 200 by 91, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 8024.197802
If we take 182 away from 200, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
When dividing 180 by 91, we get 1 with a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 8024.1978021
Deduct 91 from 180 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 14:
When dividing 890 by 91, we get 9 with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 8024.19780219
Subtracting 819 from 890 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Our division results in 8024.19780219 with a remaining 7.1e-08.
