We look at the division of 908991 by 92 
The aim is to understand the frequency of 92 in 908991.

Step 1:
If we divide 9 by 92, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 92

Advancing to step 2:
92 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 92

Moving on to step 3:
When dividing 908 by 92, we get 9 with a remainder of 80.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 828 from 908 and we're left with 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 92

Advancing to step 4:
92 goes into 809 8 times with a remainder of 73.
The next digit of our result is 8. 
Result so far: 98.0
Deduct 736 from 809 and we're left with 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 92

Going ahead to step 5:
739 divided by 92 is 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 988.0
Subtracting 736 from 739 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 92

Step 6:
92 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 9880.0
If we take 0 away from 31, we end up 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.

Step 7:
The number 92 fits into 310 3 times, leaving a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 9880.3
Subtracting 276 from 310 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
92 can be fit into 340 3 times, resulting in a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 9880.33
Subtract 276 from 340 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 9880.33 and a remainder of 0.064.
