896774 ÷ 91 
The aim is to understand the frequency of 91 in 896774.

Step 1:
8 divided by 91 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 91

Moving on to step 2:
The number 91 fits into 89 0 times, leaving a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 91

Advancing to step 3:
91 can be fit into 896 9 times, resulting in a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 819 from 896, we get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 91

On to step 4:
777 divided by 91 is 8 with a remainder of 49.
The next digit of our result is 8. 
Result so far: 98.0
The remainder is 49 after subtracting 728 from 777.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 91

Let's proceed to step 5:
When dividing 497 by 91, we get 5 with a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 985.0
Deduct 455 from 497 and we're left with 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 91

Advancing to step 6:
91 goes into 424 4 times with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 9854.0
Subtract 364 from 424 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
If we divide 600 by 91, we get 6 and a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 9854.6
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
540 divided by 91 is 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 9854.65
If we subtract 455 from 540, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 9:
When dividing 850 by 91, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 9854.659
Subtracting 819 from 850 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 10:
91 can be fit into 310 3 times, resulting in a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 9854.6593
If we take 273 away from 310, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 11:
91 goes into 370 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 9854.65934
The remainder is 6 after subtracting 364 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
If we divide 60 by 91, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 9854.65934
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
If we divide 600 by 91, we get 6 and a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 9854.6593406
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
91 goes into 540 5 times with a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 9854.65934065
If we take 455 away from 540, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 9854.65934065 with a remainder of 8.5e-08.
