We're dividing 72865854 by 122 
The aim is to understand the frequency of 122 in 72865854.

Advancing to step 1:
The number 122 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 122

On to step 2:
If we divide 72 by 122, we get 0 and a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Append the next digit (8) from the dividend to 72 and continue with: 728 / 122

Advancing to step 3:
122 can be fit into 728 5 times, resulting in a remainder of 118.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 610 from 728, we get 118.
Append the next digit (6) from the dividend to 118 and continue with: 1186 / 122

Advancing to step 4:
If we divide 1186 by 122, we get 9 and a remainder of 88.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we take 1098 away from 1186, we end up with 88.
Append the next digit (5) from the dividend to 88 and continue with: 885 / 122

Going ahead to step 5:
885 divided by 122 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 597.0
The remainder is 31 after subtracting 854 from 885.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 122

Let's proceed to step 6:
If we divide 318 by 122, we get 2 and a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 5972.0
Subtract 244 from 318 to get 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 122

Step 7:
The number 122 fits into 745 6 times, leaving a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 59726.0
Subtracting 732 from 745 leaves us with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 122

Going ahead to step 8:
122 goes into 134 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 597261.0
If we take 122 away from 134, 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 9:
120 divided by 122 is 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 597261.0
Subtracting 0 from 120 leaves us 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.

Moving on to step 10:
1200 divided by 122 is 9 with a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 597261.09
Subtracting 1098 from 1200 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 11:
1020 divided by 122 is 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 597261.098
Subtracting 976 from 1020 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
440 divided by 122 is 3 with a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 597261.0983
Subtracting 366 from 440 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 13:
When dividing 740 by 122, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 597261.09836
If we take 732 away from 740, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
If we divide 80 by 122, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 597261.09836
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 15:
If we divide 800 by 122, we get 6 and a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 597261.0983606
If we subtract 732 from 800, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 16:
122 can be fit into 680 5 times, resulting in a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 597261.09836065
Subtract 610 from 680 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 597261.09836065 with a remainder of 7e-08.
