We look at the division of 30209021 by 117 
The aim is to understand the frequency of 117 in 30209021.

Moving on to step 1:
The number 117 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 117

Moving on to step 2:
The number 117 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 117

On to step 3:
The number 117 fits into 302 2 times, leaving a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 234 away from 302, we end up with 68.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 117

Going ahead to step 4:
117 goes into 680 5 times with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 585 from 680 and we're left with 95.
Include the next digit (9) from the dividend after 95, then repeat: 959 / 117

Step 5:
117 goes into 959 8 times with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 258.0
If we take 936 away from 959, we end up with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 117

On to step 6:
If we divide 230 by 117, we get 1 and a remainder of 113.
Put 1 as the next digit of the answer. 
Result so far: 2581.0
If we take 117 away from 230, we end up with 113.
Fetch the next digit (2) from the dividend, attach it to 113 and continue: 1132 / 117

Let's proceed to step 7:
When dividing 1132 by 117, we get 9 with a remainder of 79.
The next digit of our result is 9. 
Result so far: 25819.0
Subtract 1053 from 1132 to get 79.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 117

Moving on to step 8:
791 divided by 117 is 6 with a remainder of 89.
The number 6 becomes the next digit in our result. 
Result so far: 258196.0
If we subtract 702 from 791, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 9:
890 divided by 117 is 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 258196.7
The remainder is 71 after subtracting 819 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
The number 117 fits into 710 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 258196.76
The remainder is 8 after subtracting 702 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 117, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 258196.76
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
If we divide 800 by 117, we get 6 and a remainder of 98.
The number 6 becomes the next digit in our result. 
Result so far: 258196.7606
If we take 702 away from 800, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 13:
117 goes into 980 8 times with a remainder of 44.
The next digit of our result is 8. 
Result so far: 258196.76068
If we take 936 away from 980, we end up 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.

Let's proceed to step 14:
117 goes into 440 3 times with a remainder of 89.
Use 3 as the next digit of our solution. 
Result so far: 258196.760683
If we take 351 away from 440, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 15:
The number 117 fits into 890 7 times, leaving a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 258196.7606837
Deduct 819 from 890 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 16:
When dividing 710 by 117, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 258196.76068376
If we subtract 702 from 710, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 258196.76068376 with a balance of 8e-09.
