97090554 ÷ 842 
The aim is to understand the frequency of 842 in 97090554.

On to step 1:
When dividing 9 by 842, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 842

Let's proceed to step 2:
97 divided by 842 is 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Bring next digit (0) of the dividend behind the 97 and repeat the process: 970 / 842

Moving on to step 3:
970 divided by 842 is 1 with a remainder of 128.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 842 from 970 to get 128.
Include the next digit (9) from the dividend after 128, then repeat: 1289 / 842

Advancing to step 4:
The number 842 fits into 1289 1 times, leaving a remainder of 447.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 842 from 1289, we get 447.
Include the next digit (0) from the dividend after 447, then repeat: 4470 / 842

Step 5:
4470 divided by 842 is 5 with a remainder of 260.
The next digit of our result is 5. 
Result so far: 115.0
Subtract 4210 from 4470 to get 260.
Include the next digit (5) from the dividend after 260, then repeat: 2605 / 842

Moving on to step 6:
2605 divided by 842 is 3 with a remainder of 79.
Record the quotient 3 as the next digit in the result. 
Result so far: 1153.0
The remainder is 79 after subtracting 2526 from 2605.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 842

Going ahead to step 7:
If we divide 795 by 842, we get 0 and a remainder of 795.
The number 0 becomes the next digit in our result. 
Result so far: 11530.0
Subtract 0 from 795 to get 795.
Take the next digit (4) from the dividend and append it to 795, then repeat: 7954 / 842

Step 8:
If we divide 7954 by 842, we get 9 and a remainder of 376.
Put 9 as the next digit of the answer. 
Result so far: 115309.0
Deduct 7578 from 7954 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 9:
If we divide 3760 by 842, we get 4 and a remainder of 392.
Use 4 as the next digit of our solution. 
Result so far: 115309.4
The remainder is 392 after subtracting 3368 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 10:
3920 divided by 842 is 4 with a remainder of 552.
Put 4 as the next digit of the answer. 
Result so far: 115309.44
If we subtract 3368 from 3920, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The final result is 115309.44 with a remainder of 0.552.
