We look at the division of 94821594 by 91 
The aim is to understand the frequency of 91 in 94821594.

Advancing to step 1:
91 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 91

Advancing to step 2:
If we divide 94 by 91, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 91 from 94 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 91

On to step 3:
38 divided by 91 is 0 with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 38, we end up with 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 91

Advancing to step 4:
382 divided by 91 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 104.0
If we take 364 away from 382, we end up with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 91

Going ahead to step 5:
The number 91 fits into 181 1 times, leaving a remainder of 90.
Put 1 as the next digit of the answer. 
Result so far: 1041.0
Subtract 91 from 181 to get 90.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 91

Let's proceed to step 6:
91 goes into 905 9 times with a remainder of 86.
Use 9 as the next digit of our solution. 
Result so far: 10419.0
If we subtract 819 from 905, we get 86.
Grab the next digit (9) from the dividend, add it to 86, then carry on: 869 / 91

Moving on to step 7:
The number 91 fits into 869 9 times, leaving a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 104199.0
Deduct 819 from 869 and we're left with 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 91

Step 8:
The number 91 fits into 504 5 times, leaving a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 1041995.0
Subtract 455 from 504 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
When dividing 490 by 91, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 1041995.5
Subtracting 455 from 490 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
91 can be fit into 350 3 times, resulting in a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 1041995.53
Deduct 273 from 350 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 11:
91 goes into 770 8 times with a remainder of 42.
The next digit of our result is 8. 
Result so far: 1041995.538
If we subtract 728 from 770, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
When dividing 420 by 91, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 1041995.5384
If we take 364 away from 420, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
If we divide 560 by 91, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 1041995.53846
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
The number 91 fits into 140 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 1041995.538461
Subtracting 91 from 140 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 15:
91 goes into 490 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1041995.5384615
Deduct 455 from 490 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 16:
When dividing 350 by 91, we get 3 with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 1041995.53846153
If we subtract 273 from 350, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The quotient of the division is 1041995.53846153, and the remainder is 7.7e-08.
