49546 ÷ 91 
The aim is to understand the frequency of 91 in 49546.

Step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 91

Step 2:
The number 91 fits into 49 0 times, leaving a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Append the next digit (5) from the dividend to 49 and continue with: 495 / 91

Advancing to step 3:
The number 91 fits into 495 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 455 from 495, we get 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 91

Moving on to step 4:
If we divide 404 by 91, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtracting 364 from 404 leaves us with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 91

Advancing to step 5:
When dividing 406 by 91, we get 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 544.0
The remainder is 42 after subtracting 364 from 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 6:
If we divide 420 by 91, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 544.4
Deduct 364 from 420 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
If we divide 560 by 91, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 544.46
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 91 fits into 140 1 times, leaving a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 544.461
If we subtract 91 from 140, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
91 goes into 490 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 544.4615
The remainder is 35 after subtracting 455 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
If we divide 350 by 91, we get 3 and a remainder of 77.
The next digit of our result is 3. 
Result so far: 544.46153
If we take 273 away from 350, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 11:
The number 91 fits into 770 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 544.461538
If we take 728 away from 770, we end up 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.

Going ahead to step 12:
When dividing 420 by 91, we get 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 544.4615384
Subtract 364 from 420 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
The number 91 fits into 560 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 544.46153846
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 544.46153846, and the remainder is 1.4e-08.
