We look at the division of 78411672 by 122 
The aim is to understand the frequency of 122 in 78411672.

Moving on to step 1:
122 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 122

Going ahead to step 2:
When dividing 78 by 122, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 122

On to step 3:
If we divide 784 by 122, we get 6 and a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 732 from 784, we get 52.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 122

Moving on to step 4:
If we divide 521 by 122, we get 4 and a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Subtracting 488 from 521 leaves us with 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 122

Advancing to step 5:
122 can be fit into 331 2 times, resulting in a remainder of 87.
Use 2 as the next digit of our solution. 
Result so far: 642.0
Deduct 244 from 331 and we're left with 87.
Take the next digit (6) from the dividend and append it to 87, then repeat: 876 / 122

On to step 6:
122 can be fit into 876 7 times, resulting in a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 6427.0
Subtracting 854 from 876 leaves us with 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 122

Going ahead to step 7:
122 can be fit into 227 1 times, resulting in a remainder of 105.
Write down 1 as next digit of the result. 
Result so far: 64271.0
Subtracting 122 from 227 leaves us with 105.
Append the next digit (2) from the dividend to 105 and continue with: 1052 / 122

On to step 8:
122 can be fit into 1052 8 times, resulting in a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 642718.0
Subtracting 976 from 1052 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
122 can be fit into 760 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 642718.6
Deduct 732 from 760 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
The number 122 fits into 280 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 642718.62
Subtracting 244 from 280 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
The number 122 fits into 360 2 times, leaving a remainder of 116.
The number 2 becomes the next digit in our result. 
Result so far: 642718.622
If we subtract 244 from 360, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Our division results in 642718.622 with a remaining 0.0116.
