655105 ÷ 91 
The aim is to understand the frequency of 91 in 655105.

Let's proceed to step 1:
91 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 91

On to step 2:
91 goes into 65 0 times with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 91

Going ahead to step 3:
When dividing 655 by 91, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 637 from 655, we get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 91

Moving on to step 4:
91 goes into 181 1 times with a remainder of 90.
Write down 1 as next digit of the result. 
Result so far: 71.0
The remainder is 90 after subtracting 91 from 181.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 91

Going ahead to step 5:
The number 91 fits into 900 9 times, leaving a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 719.0
The remainder is 81 after subtracting 819 from 900.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 91

Advancing to step 6:
When dividing 815 by 91, we get 8 with a remainder of 87.
Write down 8 as next digit of the result. 
Result so far: 7198.0
If we take 728 away from 815, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 7:
The number 91 fits into 870 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 7198.9
Subtract 819 from 870 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 8:
When dividing 510 by 91, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 7198.95
If we take 455 away from 510, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 9:
If we divide 550 by 91, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 7198.956
The remainder is 4 after subtracting 546 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
The number 91 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 7198.956
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
The number 91 fits into 400 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 7198.95604
If we take 364 away from 400, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
When dividing 360 by 91, we get 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 7198.956043
Deduct 273 from 360 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 13:
870 divided by 91 is 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 7198.9560439
Deduct 819 from 870 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 14:
510 divided by 91 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 7198.95604395
Subtract 455 from 510 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 7198.95604395 and a remainder of 5.5e-08.
