75228855 ÷ 117 
The aim is to understand the frequency of 117 in 75228855.

On to step 1:
When dividing 7 by 117, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 117

Step 2:
If we divide 75 by 117, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Fetch the next digit (2) from the dividend, attach it to 75 and continue: 752 / 117

Let's proceed to step 3:
752 divided by 117 is 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 702 from 752, we get 50.
Append the next digit (2) from the dividend to 50 and continue with: 502 / 117

Moving on to step 4:
The number 117 fits into 502 4 times, leaving a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 34 after subtracting 468 from 502.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 117

Moving on to step 5:
If we divide 348 by 117, we get 2 and a remainder of 114.
The number 2 becomes the next digit in our result. 
Result so far: 642.0
Subtracting 234 from 348 leaves us with 114.
Grab the next digit (8) from the dividend, add it to 114, then carry on: 1148 / 117

Advancing to step 6:
117 can be fit into 1148 9 times, resulting in a remainder of 95.
The number 9 becomes the next digit in our result. 
Result so far: 6429.0
The remainder is 95 after subtracting 1053 from 1148.
Append the next digit (5) from the dividend to 95 and continue with: 955 / 117

Step 7:
If we divide 955 by 117, we get 8 and a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 64298.0
The remainder is 19 after subtracting 936 from 955.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 117

On to step 8:
117 can be fit into 195 1 times, resulting in a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 642981.0
If we take 117 away from 195, we end up 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.

Step 9:
When dividing 780 by 117, we get 6 with a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 642981.6
If we take 702 away from 780, we end up 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.

Moving on to step 10:
When dividing 780 by 117, we get 6 with a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 642981.66
Subtracting 702 from 780 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.

After the division, we end up with 642981.66 and a remainder of 0.078.
