We look at the division of 218636 by 97 
The aim is to understand the frequency of 97 in 218636.

Let's proceed to step 1:
2 divided by 97 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 97

Let's proceed to step 2:
97 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 97

Step 3:
97 goes into 218 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 194 from 218 leaves us with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 97

Let's proceed to step 4:
246 divided by 97 is 2 with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Deduct 194 from 246 and we're left with 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 97

Advancing to step 5:
97 goes into 523 5 times with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 225.0
If we take 485 away from 523, we end up with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 97

Step 6:
386 divided by 97 is 3 with a remainder of 95.
Write down 3 as next digit of the result. 
Result so far: 2253.0
If we take 291 away from 386, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 7:
97 goes into 950 9 times with a remainder of 77.
Record the quotient 9 as the next digit in the result. 
Result so far: 2253.9
Subtract 873 from 950 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 8:
97 can be fit into 770 7 times, resulting in a remainder of 91.
Put 7 as the next digit of the answer. 
Result so far: 2253.97
Deduct 679 from 770 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 9:
If we divide 910 by 97, we get 9 and a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 2253.979
Deduct 873 from 910 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
If we divide 370 by 97, we get 3 and a remainder of 79.
Record the quotient 3 as the next digit in the result. 
Result so far: 2253.9793
If we subtract 291 from 370, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 11:
97 goes into 790 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 2253.97938
If we take 776 away from 790, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
The number 97 fits into 140 1 times, leaving a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 2253.979381
If we subtract 97 from 140, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
The number 97 fits into 430 4 times, leaving a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 2253.9793814
If we take 388 away from 430, we end up 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.

Step 14:
When dividing 420 by 97, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 2253.97938144
Deduct 388 from 420 and we're left 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.

After the division, we end up with 2253.97938144 and a remainder of 3.2e-08.
