640341 divided by 97 
The aim is to understand the frequency of 97 in 640341.

Moving on to step 1:
The number 97 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 97

Let's proceed to step 2:
97 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 97

Advancing to step 3:
If we divide 640 by 97, we get 6 and a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 582 from 640 and we're left with 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 97

Moving on to step 4:
583 divided by 97 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we take 582 away from 583, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 97

Step 5:
The number 97 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 660.0
Subtracting 0 from 14 leaves us with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 97

Moving on to step 6:
If we divide 141 by 97, we get 1 and a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 6601.0
The remainder is 44 after subtracting 97 from 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
440 divided by 97 is 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 6601.4
If we subtract 388 from 440, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
If we divide 520 by 97, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 6601.45
If we take 485 away from 520, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
The number 97 fits into 350 3 times, leaving a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 6601.453
Subtract 291 from 350 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
When dividing 590 by 97, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6601.4536
Subtract 582 from 590 to 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.

Step 11:
80 divided by 97 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 6601.4536
If we take 0 away from 80, we end up with 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:
97 can be fit into 800 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 6601.453608
If we take 776 away from 800, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
The number 97 fits into 240 2 times, leaving a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 6601.4536082
If we take 194 away from 240, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
The number 97 fits into 460 4 times, leaving a remainder of 72.
The next digit of our result is 4. 
Result so far: 6601.45360824
The remainder is 72 after subtracting 388 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 6601.45360824 and a remainder of 7.2e-08.
