642861 ÷ 97 
The aim is to understand the frequency of 97 in 642861.

Going ahead to step 1:
The number 97 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 97

Advancing to step 2:
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: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 97

Moving on to step 3:
97 can be fit into 642 6 times, resulting in a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 582 away from 642, we end up with 60.
Include the next digit (8) from the dividend after 60, then repeat: 608 / 97

On to step 4:
97 can be fit into 608 6 times, resulting in a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we subtract 582 from 608, we get 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 97

On to step 5:
If we divide 266 by 97, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 662.0
Subtracting 194 from 266 leaves us with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 97

Going ahead to step 6:
721 divided by 97 is 7 with a remainder of 42.
The next digit of our result is 7. 
Result so far: 6627.0
Subtracting 679 from 721 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
420 divided by 97 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 6627.4
The remainder is 32 after subtracting 388 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
The number 97 fits into 320 3 times, leaving a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 6627.43
Subtracting 291 from 320 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
290 divided by 97 is 2 with a remainder of 96.
The next digit of our result is 2. 
Result so far: 6627.432
Deduct 194 from 290 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 10:
960 divided by 97 is 9 with a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 6627.4329
The remainder is 87 after subtracting 873 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 11:
When dividing 870 by 97, we get 8 with a remainder of 94.
Use 8 as the next digit of our solution. 
Result so far: 6627.43298
Deduct 776 from 870 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 12:
940 divided by 97 is 9 with a remainder of 67.
The next digit of our result is 9. 
Result so far: 6627.432989
Deduct 873 from 940 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 13:
The number 97 fits into 670 6 times, leaving a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 6627.4329896
The remainder is 88 after subtracting 582 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 14:
The number 97 fits into 880 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 6627.43298969
The remainder is 7 after subtracting 873 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 6627.43298969 with a remainder of 7e-09.
