Let's divide 921420 by 97
The aim is to understand the frequency of 97 in 921420.

Step 1:
If we divide 9 by 97, 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.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 97

Going ahead to step 2:
If we divide 92 by 97, we get 0 and a remainder of 92.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 92 and we're left with 92.
Bring next digit (1) of the dividend behind the 92 and repeat the process: 921 / 97

Moving on to step 3:
The number 97 fits into 921 9 times, leaving a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 873 from 921 and we're left with 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 97

Advancing to step 4:
When dividing 484 by 97, we get 4 with a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
If we take 388 away from 484, we end up with 96.
Append the next digit (2) from the dividend to 96 and continue with: 962 / 97

Step 5:
The number 97 fits into 962 9 times, leaving a remainder of 89.
The next digit of our result is 9. 
Result so far: 949.0
Subtract 873 from 962 to get 89.
Take the next digit (0) from the dividend and append it to 89, then repeat: 890 / 97

Let's proceed to step 6:
If we divide 890 by 97, we get 9 and a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 9499.0
Subtract 873 from 890 to 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.

Advancing to step 7:
If we divide 170 by 97, we get 1 and a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 9499.1
If we take 97 away from 170, we end up 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.

Let's proceed to step 8:
If we divide 730 by 97, we get 7 and a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 9499.17
Subtracting 679 from 730 leaves us 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.

Step 9:
97 goes into 510 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 9499.175
Subtract 485 from 510 to get 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 10:
If we divide 250 by 97, we get 2 and a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 9499.1752
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.

Let's proceed to step 11:
560 divided by 97 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 9499.17525
Subtracting 485 from 560 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 12:
97 can be fit into 750 7 times, resulting in a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 9499.175257
Subtract 679 from 750 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 13:
The number 97 fits into 710 7 times, leaving a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 9499.1752577
Deduct 679 from 710 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 9499.1752577, with a leftover of 3.1e-07.
