We divide 645372 by 97
The aim is to understand the frequency of 97 in 645372.

Advancing to step 1:
97 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 97

On to step 2:
If we divide 64 by 97, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 97

On to step 3:
97 goes into 645 6 times with a remainder of 63.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 582 from 645, we get 63.
Bring next digit (3) of the dividend behind the 63 and repeat the process: 633 / 97

Advancing to step 4:
If we divide 633 by 97, we get 6 and a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 66.0
If we take 582 away from 633, we end up with 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 97

Moving on to step 5:
517 divided by 97 is 5 with a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 665.0
If we subtract 485 from 517, we get 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 97

Going ahead to step 6:
97 goes into 322 3 times with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 6653.0
The remainder is 31 after subtracting 291 from 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
310 divided by 97 is 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 6653.3
Subtract 291 from 310 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
97 goes into 190 1 times with a remainder of 93.
The number 1 becomes the next digit in our result. 
Result so far: 6653.31
Deduct 97 from 190 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 9:
If we divide 930 by 97, we get 9 and a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 6653.319
Subtracting 873 from 930 leaves us 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.

Going ahead to step 10:
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: 6653.3195
The remainder is 85 after subtracting 485 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 11:
850 divided by 97 is 8 with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 6653.31958
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.

Step 12:
740 divided by 97 is 7 with a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 6653.319587
If we take 679 away from 740, we end up with 61.
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 13:
When dividing 610 by 97, we get 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 6653.3195876
Subtracting 582 from 610 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
280 divided by 97 is 2 with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 6653.31958762
If we take 194 away from 280, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 6653.31958762 with a remaining 8.6e-08.
