Let's divide 90579525 by 122
The aim is to understand the frequency of 122 in 90579525.

Advancing to step 1:
If we divide 9 by 122, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 122

Moving on to step 2:
122 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Grab the next digit (5) from the dividend, add it to 90, then carry on: 905 / 122

On to step 3:
905 divided by 122 is 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 854 from 905 leaves us with 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 122

Let's proceed to step 4:
When dividing 517 by 122, we get 4 with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 74.0
The remainder is 29 after subtracting 488 from 517.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 122

Let's proceed to step 5:
299 divided by 122 is 2 with a remainder of 55.
Put 2 as the next digit of the answer. 
Result so far: 742.0
Deduct 244 from 299 and we're left with 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 122

Let's proceed to step 6:
The number 122 fits into 555 4 times, leaving a remainder of 67.
Put 4 as the next digit of the answer. 
Result so far: 7424.0
Deduct 488 from 555 and we're left with 67.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 122

Going ahead to step 7:
672 divided by 122 is 5 with a remainder of 62.
Put 5 as the next digit of the answer. 
Result so far: 74245.0
Subtracting 610 from 672 leaves us with 62.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 122

Let's proceed to step 8:
122 can be fit into 625 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 742455.0
Subtract 610 from 625 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
150 divided by 122 is 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 742455.1
Subtract 122 from 150 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
122 goes into 280 2 times with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 742455.12
If we take 244 away from 280, we end up 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.

Moving on to step 11:
If we divide 360 by 122, we get 2 and a remainder of 116.
The next digit of our result is 2. 
Result so far: 742455.122
Subtract 244 from 360 to 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.

The final outcome is 742455.122, with a leftover of 0.0116.
