Let's divide 205815 by 97
The aim is to understand the frequency of 97 in 205815.

Step 1:
If we divide 2 by 97, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 97

On to step 2:
The number 97 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 97

Step 3:
97 goes into 205 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 194 from 205 leaves us with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 97

Going ahead to step 4:
97 goes into 118 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 97 from 118 leaves us with 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 97

Moving on to step 5:
If we divide 211 by 97, we get 2 and a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
If we subtract 194 from 211, we get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 97

Step 6:
97 goes into 175 1 times with a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 2121.0
If we subtract 97 from 175, we get 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 7:
The number 97 fits into 780 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 2121.8
Subtract 776 from 780 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
If we divide 40 by 97, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 2121.8
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 97, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 2121.804
If we take 388 away from 400, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
97 goes into 120 1 times with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 2121.8041
Subtracting 97 from 120 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
When dividing 230 by 97, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 2121.80412
Subtracting 194 from 230 leaves us 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.

Let's proceed to step 12:
360 divided by 97 is 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 2121.804123
If we take 291 away from 360, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 13:
When dividing 690 by 97, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 2121.8041237
Deduct 679 from 690 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
If we divide 110 by 97, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 2121.80412371
Deduct 97 from 110 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 2121.80412371 with a balance of 1.3e-08.
