We look at the division of 93627315 by 121 
The aim is to understand the frequency of 121 in 93627315.

Going ahead to step 1:
When dividing 9 by 121, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 121

Let's proceed to step 2:
If we divide 93 by 121, we get 0 and a remainder of 93.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 93, we get 93.
Include the next digit (6) from the dividend after 93, then repeat: 936 / 121

Let's proceed to step 3:
If we divide 936 by 121, we get 7 and a remainder of 89.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 847 from 936, we get 89.
Include the next digit (2) from the dividend after 89, then repeat: 892 / 121

Let's proceed to step 4:
121 goes into 892 7 times with a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 77.0
The remainder is 45 after subtracting 847 from 892.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 121

Going ahead to step 5:
457 divided by 121 is 3 with a remainder of 94.
Record the quotient 3 as the next digit in the result. 
Result so far: 773.0
If we subtract 363 from 457, we get 94.
Grab the next digit (3) from the dividend, add it to 94, then carry on: 943 / 121

Going ahead to step 6:
943 divided by 121 is 7 with a remainder of 96.
The next digit of our result is 7. 
Result so far: 7737.0
If we subtract 847 from 943, we get 96.
Grab the next digit (1) from the dividend, add it to 96, then carry on: 961 / 121

Moving on to step 7:
If we divide 961 by 121, we get 7 and a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 77377.0
Subtract 847 from 961 to get 114.
Grab the next digit (5) from the dividend, add it to 114, then carry on: 1145 / 121

Going ahead to step 8:
1145 divided by 121 is 9 with a remainder of 56.
The next digit of our result is 9. 
Result so far: 773779.0
Subtract 1089 from 1145 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
The number 121 fits into 560 4 times, leaving a remainder of 76.
The next digit of our result is 4. 
Result so far: 773779.4
The remainder is 76 after subtracting 484 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
If we divide 760 by 121, we get 6 and a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 773779.46
Subtracting 726 from 760 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 11:
121 goes into 340 2 times with a remainder of 98.
The number 2 becomes the next digit in our result. 
Result so far: 773779.462
Deduct 242 from 340 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 12:
If we divide 980 by 121, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 773779.4628
If we take 968 away from 980, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
121 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 773779.4628
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
121 goes into 1200 9 times with a remainder of 111.
Write down 9 as next digit of the result. 
Result so far: 773779.462809
If we subtract 1089 from 1200, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 15:
121 can be fit into 1110 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 773779.4628099
Subtracting 1089 from 1110 leaves us 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.

In conclusion, the division gives 773779.4628099 with a balance of 2.1e-07.
