Let's divide 290378 by 97
The aim is to understand the frequency of 97 in 290378.

On to step 1:
97 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 97

Step 2:
97 goes into 29 0 times with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 97

On to step 3:
If we divide 290 by 97, we get 2 and a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 194 from 290 and we're left with 96.
Take the next digit (3) from the dividend and append it to 96, then repeat: 963 / 97

Advancing to step 4:
97 goes into 963 9 times with a remainder of 90.
The next digit of our result is 9. 
Result so far: 29.0
The remainder is 90 after subtracting 873 from 963.
Append the next digit (7) from the dividend to 90 and continue with: 907 / 97

Step 5:
The number 97 fits into 907 9 times, leaving a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 299.0
If we take 873 away from 907, we end up with 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 97

Advancing to step 6:
The number 97 fits into 348 3 times, leaving a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 2993.0
Deduct 291 from 348 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
If we divide 570 by 97, we get 5 and a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 2993.5
Subtracting 485 from 570 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 8:
850 divided by 97 is 8 with a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 2993.58
Subtract 776 from 850 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
97 goes into 740 7 times with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 2993.587
The remainder is 61 after subtracting 679 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 10:
97 can be fit into 610 6 times, resulting in a remainder of 28.
The next digit of our result is 6. 
Result so far: 2993.5876
If we subtract 582 from 610, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
280 divided by 97 is 2 with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 2993.58762
If we subtract 194 from 280, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 12:
97 can be fit into 860 8 times, resulting in a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 2993.587628
Subtracting 776 from 860 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 13:
The number 97 fits into 840 8 times, leaving a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 2993.5876288
The remainder is 64 after subtracting 776 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 2993.5876288 with a remaining 6.4e-07.
