We look at the division of 661311 by 97 
The aim is to understand the frequency of 97 in 661311.

Let's proceed to step 1:
97 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 97

Moving on to step 2:
When dividing 66 by 97, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 97

Advancing to step 3:
97 can be fit into 661 6 times, resulting in a remainder of 79.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 582 from 661 to get 79.
Grab the next digit (3) from the dividend, add it to 79, then carry on: 793 / 97

Going ahead to step 4:
97 can be fit into 793 8 times, resulting in a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Subtracting 776 from 793 leaves us with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 97

Let's proceed to step 5:
When dividing 171 by 97, we get 1 with a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 681.0
If we take 97 away from 171, we end up with 74.
Grab the next digit (1) from the dividend, add it to 74, then carry on: 741 / 97

Step 6:
The number 97 fits into 741 7 times, leaving a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 6817.0
Deduct 679 from 741 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
If we divide 620 by 97, we get 6 and a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 6817.6
Deduct 582 from 620 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
If we divide 380 by 97, we get 3 and a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 6817.63
If we take 291 away from 380, 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.

Advancing to step 9:
890 divided by 97 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 6817.639
If we subtract 873 from 890, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
The number 97 fits into 170 1 times, leaving a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 6817.6391
Subtracting 97 from 170 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 11:
When dividing 730 by 97, we get 7 with a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 6817.63917
If we take 679 away from 730, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 12:
When dividing 510 by 97, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 6817.639175
Deduct 485 from 510 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
If we divide 250 by 97, we get 2 and a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 6817.6391752
Deduct 194 from 250 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 14:
The number 97 fits into 560 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 6817.63917525
If we subtract 485 from 560, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

In conclusion, the division gives 6817.63917525 with a balance of 7.5e-08.
