We look at the division of 97199866 by 318 
The aim is to understand the frequency of 318 in 97199866.

On to step 1:
If we divide 9 by 318, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 318

Moving on to step 2:
If we divide 97 by 318, we get 0 and a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Grab the next digit (1) from the dividend, add it to 97, then carry on: 971 / 318

Step 3:
971 divided by 318 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 954 from 971 and we're left with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 318

Advancing to step 4:
318 goes into 179 0 times with a remainder of 179.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtracting 0 from 179 leaves us with 179.
Bring next digit (9) of the dividend behind the 179 and repeat the process: 1799 / 318

Let's proceed to step 5:
318 goes into 1799 5 times with a remainder of 209.
Record the quotient 5 as the next digit in the result. 
Result so far: 305.0
Subtracting 1590 from 1799 leaves us with 209.
Append the next digit (8) from the dividend to 209 and continue with: 2098 / 318

Let's proceed to step 6:
The number 318 fits into 2098 6 times, leaving a remainder of 190.
The number 6 becomes the next digit in our result. 
Result so far: 3056.0
The remainder is 190 after subtracting 1908 from 2098.
Append the next digit (6) from the dividend to 190 and continue with: 1906 / 318

Going ahead to step 7:
When dividing 1906 by 318, we get 5 with a remainder of 316.
Put 5 as the next digit of the answer. 
Result so far: 30565.0
Subtracting 1590 from 1906 leaves us with 316.
Take the next digit (6) from the dividend and append it to 316, then repeat: 3166 / 318

Moving on to step 8:
If we divide 3166 by 318, we get 9 and a remainder of 304.
Put 9 as the next digit of the answer. 
Result so far: 305659.0
If we subtract 2862 from 3166, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 9:
If we divide 3040 by 318, we get 9 and a remainder of 178.
The number 9 becomes the next digit in our result. 
Result so far: 305659.9
The remainder is 178 after subtracting 2862 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 10:
The number 318 fits into 1780 5 times, leaving a remainder of 190.
The next digit of our result is 5. 
Result so far: 305659.95
Subtracting 1590 from 1780 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
318 goes into 1900 5 times with a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 305659.955
Subtracting 1590 from 1900 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

In conclusion, the division gives 305659.955 with a balance of 0.031.
