We're dividing 743382 by 91 
The aim is to understand the frequency of 91 in 743382.

Step 1:
If we divide 7 by 91, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 91

Going ahead to step 2:
74 divided by 91 is 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Append the next digit (3) from the dividend to 74 and continue with: 743 / 91

Step 3:
If we divide 743 by 91, we get 8 and a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 15 after subtracting 728 from 743.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 91

On to step 4:
The number 91 fits into 153 1 times, leaving a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we take 91 away from 153, we end up with 62.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 91

Moving on to step 5:
The number 91 fits into 628 6 times, leaving a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 816.0
If we take 546 away from 628, we end up with 82.
Append the next digit (2) from the dividend to 82 and continue with: 822 / 91

Moving on to step 6:
822 divided by 91 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 8169.0
Subtracting 819 from 822 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 7:
91 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 8169.0
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 8:
300 divided by 91 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 8169.03
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
The number 91 fits into 270 2 times, leaving a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 8169.032
If we take 182 away from 270, we end up 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 10:
When dividing 880 by 91, we get 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 8169.0329
The remainder is 61 after subtracting 819 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 11:
610 divided by 91 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 8169.03296
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.

On to step 12:
If we divide 640 by 91, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 8169.032967
If we take 637 away from 640, we end up 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.

On to step 13:
91 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 8169.032967
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.

On to step 14:
When dividing 300 by 91, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 8169.03296703
If we take 273 away from 300, we end up 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.

The quotient of the division is 8169.03296703, and the remainder is 2.7e-08.
