Let's divide 24602687 by 121
The aim is to understand the frequency of 121 in 24602687.

Advancing to step 1:
If we divide 2 by 121, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 121

Moving on to step 2:
The number 121 fits into 24 0 times, leaving a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 121

On to step 3:
121 goes into 246 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we take 242 away from 246, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 121

Step 4:
When dividing 40 by 121, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 121

Moving on to step 5:
If we divide 402 by 121, we get 3 and a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 203.0
Subtracting 363 from 402 leaves us with 39.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 121

Advancing to step 6:
121 can be fit into 396 3 times, resulting in a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 2033.0
Deduct 363 from 396 and we're left with 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 121

On to step 7:
121 goes into 338 2 times with a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 20332.0
If we subtract 242 from 338, we get 96.
Fetch the next digit (7) from the dividend, attach it to 96 and continue: 967 / 121

Step 8:
When dividing 967 by 121, we get 7 with a remainder of 120.
The next digit of our result is 7. 
Result so far: 203327.0
If we take 847 away from 967, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
121 can be fit into 1200 9 times, resulting in a remainder of 111.
The next digit of our result is 9. 
Result so far: 203327.9
The remainder is 111 after subtracting 1089 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 10:
The number 121 fits into 1110 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 203327.99
Deduct 1089 from 1110 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.

After the division, we end up with 203327.99 and a remainder of 0.021.
