We're dividing 91497257 by 122 
The aim is to understand the frequency of 122 in 91497257.

Step 1:
9 divided by 122 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 122

Moving on to step 2:
When dividing 91 by 122, we get 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Append the next digit (4) from the dividend to 91 and continue with: 914 / 122

Step 3:
122 goes into 914 7 times with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 854 from 914 leaves us with 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 122

Going ahead to step 4:
The number 122 fits into 609 4 times, leaving a remainder of 121.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we take 488 away from 609, we end up with 121.
Bring next digit (7) of the dividend behind the 121 and repeat the process: 1217 / 122

Step 5:
When dividing 1217 by 122, we get 9 with a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 749.0
Deduct 1098 from 1217 and we're left with 119.
Append the next digit (2) from the dividend to 119 and continue with: 1192 / 122

Advancing to step 6:
If we divide 1192 by 122, we get 9 and a remainder of 94.
The next digit of our result is 9. 
Result so far: 7499.0
If we take 1098 away from 1192, we end up with 94.
Bring next digit (5) of the dividend behind the 94 and repeat the process: 945 / 122

Going ahead to step 7:
When dividing 945 by 122, we get 7 with a remainder of 91.
The number 7 becomes the next digit in our result. 
Result so far: 74997.0
Deduct 854 from 945 and we're left with 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 122

Let's proceed to step 8:
When dividing 917 by 122, we get 7 with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 749977.0
Subtract 854 from 917 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
630 divided by 122 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 749977.5
If we subtract 610 from 630, we 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.

Step 10:
122 goes into 200 1 times with a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 749977.51
Subtracting 122 from 200 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 11:
122 can be fit into 780 6 times, resulting in a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 749977.516
If we subtract 732 from 780, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
The number 122 fits into 480 3 times, leaving a remainder of 114.
The next digit of our result is 3. 
Result so far: 749977.5163
The remainder is 114 after subtracting 366 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 13:
If we divide 1140 by 122, we get 9 and a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 749977.51639
Deduct 1098 from 1140 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
If we divide 420 by 122, we get 3 and a remainder of 54.
The next digit of our result is 3. 
Result so far: 749977.516393
If we take 366 away from 420, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 15:
The number 122 fits into 540 4 times, leaving a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 749977.5163934
Subtracting 488 from 540 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 16:
If we divide 520 by 122, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 749977.51639344
Subtracting 488 from 520 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 749977.51639344 with a remainder of 3.2e-08.
