549576 ÷ 91 
The aim is to understand the frequency of 91 in 549576.

Moving on to step 1:
91 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 91

Moving on to step 2:
The number 91 fits into 54 0 times, leaving a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 91

Going ahead to step 3:
When dividing 549 by 91, we get 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 546 away from 549, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 91

Step 4:
The number 91 fits into 35 0 times, leaving a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
The remainder is 35 after subtracting 0 from 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 91

On to step 5:
357 divided by 91 is 3 with a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 603.0
Subtract 273 from 357 to get 84.
Append the next digit (6) from the dividend to 84 and continue with: 846 / 91

On to step 6:
91 goes into 846 9 times with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 6039.0
Deduct 819 from 846 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
91 can be fit into 270 2 times, resulting in a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 6039.2
If we subtract 182 from 270, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 8:
91 can be fit into 880 9 times, resulting in a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 6039.29
If we subtract 819 from 880, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
91 can be fit into 610 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 6039.296
Subtracting 546 from 610 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
The number 91 fits into 640 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 6039.2967
Subtracting 637 from 640 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
91 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 6039.2967
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
When dividing 300 by 91, we get 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 6039.296703
The remainder is 27 after subtracting 273 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
270 divided by 91 is 2 with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 6039.2967032
Deduct 182 from 270 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 14:
If we divide 880 by 91, we get 9 and a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 6039.29670329
If we take 819 away from 880, 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.

Our division results in 6039.29670329 with a remaining 6.1e-08.
