We look at the division of 58336291 by 121 
The aim is to understand the frequency of 121 in 58336291.

Advancing to step 1:
121 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 121

Going ahead to step 2:
If we divide 58 by 121, we get 0 and a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Bring next digit (3) of the dividend behind the 58 and repeat the process: 583 / 121

Step 3:
When dividing 583 by 121, we get 4 with a remainder of 99.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 99 after subtracting 484 from 583.
Fetch the next digit (3) from the dividend, attach it to 99 and continue: 993 / 121

On to step 4:
121 goes into 993 8 times with a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 48.0
Deduct 968 from 993 and we're left with 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 121

On to step 5:
If we divide 256 by 121, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 482.0
The remainder is 14 after subtracting 242 from 256.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 121

Advancing to step 6:
If we divide 142 by 121, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 4821.0
If we subtract 121 from 142, we get 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 121

Going ahead to step 7:
When dividing 219 by 121, we get 1 with a remainder of 98.
Record the quotient 1 as the next digit in the result. 
Result so far: 48211.0
Subtract 121 from 219 to get 98.
Include the next digit (1) from the dividend after 98, then repeat: 981 / 121

Moving on to step 8:
981 divided by 121 is 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 482118.0
If we subtract 968 from 981, we 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.

Let's proceed to step 9:
130 divided by 121 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 482118.1
Subtract 121 from 130 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
The number 121 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 482118.1
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
121 can be fit into 900 7 times, resulting in a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 482118.107
The remainder is 53 after subtracting 847 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 12:
The number 121 fits into 530 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 482118.1074
If we take 484 away from 530, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
121 can be fit into 460 3 times, resulting in a remainder of 97.
The next digit of our result is 3. 
Result so far: 482118.10743
If we subtract 363 from 460, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 14:
970 divided by 121 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 482118.107438
If we take 968 away from 970, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 15:
When dividing 20 by 121, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 482118.107438
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
200 divided by 121 is 1 with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 482118.10743801
Deduct 121 from 200 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The quotient of the division is 482118.10743801, and the remainder is 7.9e-08.
