We divide 910084 by 91
The aim is to understand the frequency of 91 in 910084.

Step 1:
9 divided by 91 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 91

Moving on to step 2:
91 divided by 91 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 91 from 91 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 91

Let's proceed to step 3:
The number 91 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 91

Moving on to step 4:
91 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtract 0 from 0 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 91

Step 5:
91 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 1000.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 91

Moving on to step 6:
If we divide 84 by 91, we get 0 and a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 10000.0
If we subtract 0 from 84, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 7:
91 can be fit into 840 9 times, resulting in a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 10000.9
Subtracting 819 from 840 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
When dividing 210 by 91, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 10000.92
Subtracting 182 from 210 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
91 can be fit into 280 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 10000.923
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
If we divide 70 by 91, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10000.923
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
When dividing 700 by 91, we get 7 with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 10000.92307
The remainder is 63 after subtracting 637 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 12:
If we divide 630 by 91, we get 6 and a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 10000.923076
Subtracting 546 from 630 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 13:
91 can be fit into 840 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 10000.9230769
Deduct 819 from 840 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 14:
210 divided by 91 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 10000.92307692
If we subtract 182 from 210, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 10000.92307692 with a remaining 2.8e-08.
