We look at the division of 8560092 by 121 
The aim is to understand the frequency of 121 in 8560092.

Advancing to step 1:
When dividing 8 by 121, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 121

Advancing to step 2:
121 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Append the next digit (6) from the dividend to 85 and continue with: 856 / 121

Advancing to step 3:
856 divided by 121 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 847 from 856, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 121

Moving on to step 4:
When dividing 90 by 121, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we take 0 away from 90, we end up with 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 121

On to step 5:
When dividing 900 by 121, we get 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 707.0
Deduct 847 from 900 and we're left with 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 121

Step 6:
121 can be fit into 539 4 times, resulting in a remainder of 55.
The number 4 becomes the next digit in our result. 
Result so far: 7074.0
If we take 484 away from 539, we end up with 55.
Bring next digit (2) of the dividend behind the 55 and repeat the process: 552 / 121

Going ahead to step 7:
121 can be fit into 552 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 70744.0
Deduct 484 from 552 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
If we divide 680 by 121, we get 5 and a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 70744.5
Subtract 605 from 680 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
121 goes into 750 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 70744.56
If we take 726 away from 750, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
121 goes into 240 1 times with a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 70744.561
If we take 121 away from 240, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 11:
121 goes into 1190 9 times with a remainder of 101.
Use 9 as the next digit of our solution. 
Result so far: 70744.5619
Subtracting 1089 from 1190 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 12:
121 goes into 1010 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 70744.56198
Deduct 968 from 1010 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
If we divide 420 by 121, we get 3 and a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 70744.561983
Deduct 363 from 420 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 14:
570 divided by 121 is 4 with a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 70744.5619834
If we subtract 484 from 570, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 15:
121 goes into 860 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 70744.56198347
Subtract 847 from 860 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 70744.56198347 with a remaining 1.3e-08.
