We look at the division of 421044 by 97 
The aim is to understand the frequency of 97 in 421044.

On to step 1:
97 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 97

Advancing to step 2:
97 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 97

Step 3:
The number 97 fits into 421 4 times, leaving a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 33 after subtracting 388 from 421.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 97

Advancing to step 4:
The number 97 fits into 330 3 times, leaving a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 291 from 330 leaves us with 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 97

Let's proceed to step 5:
394 divided by 97 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 434.0
Deduct 388 from 394 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 97

Let's proceed to step 6:
97 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 4340.0
If we take 0 away from 64, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 7:
640 divided by 97 is 6 with a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 4340.6
Subtracting 582 from 640 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
If we divide 580 by 97, we get 5 and a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 4340.65
If we subtract 485 from 580, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 9:
If we divide 950 by 97, we get 9 and a remainder of 77.
Use 9 as the next digit of our solution. 
Result so far: 4340.659
If we subtract 873 from 950, we 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.

Let's proceed to step 10:
770 divided by 97 is 7 with a remainder of 91.
Record the quotient 7 as the next digit in the result. 
Result so far: 4340.6597
If we subtract 679 from 770, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 11:
97 can be fit into 910 9 times, resulting in a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 4340.65979
Subtracting 873 from 910 leaves us 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.

Moving on to step 12:
When dividing 370 by 97, we get 3 with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 4340.659793
If we take 291 away from 370, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 13:
97 goes into 790 8 times with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 4340.6597938
Subtract 776 from 790 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
97 goes into 140 1 times with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 4340.65979381
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.

The final outcome is 4340.65979381, with a leftover of 4.3e-08.
