Let's divide 49141 by 91
The aim is to understand the frequency of 91 in 49141.

On to step 1:
91 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 91

Step 2:
If we divide 49 by 91, we get 0 and a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 91

Let's proceed to step 3:
91 can be fit into 491 5 times, resulting in a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 455 from 491 to get 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 91

Moving on to step 4:
364 divided by 91 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 54.0
Deduct 364 from 364 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 91

Step 5:
91 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 540.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 6:
The number 91 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 540.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
The number 91 fits into 100 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 540.01
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
When dividing 90 by 91, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 540.01
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
If we divide 900 by 91, we get 9 and a remainder of 81.
The next digit of our result is 9. 
Result so far: 540.0109
Deduct 819 from 900 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 10:
If we divide 810 by 91, we get 8 and a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 540.01098
Subtracting 728 from 810 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 11:
The number 91 fits into 820 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 540.010989
The remainder is 1 after subtracting 819 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
91 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 540.010989
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
100 divided by 91 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 540.01098901
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 540.01098901 with a remaining 9e-09.
