We divide 883740 by 91
The aim is to understand the frequency of 91 in 883740.

Advancing to step 1:
The number 91 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 91

Step 2:
91 goes into 88 0 times with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Take the next digit (3) from the dividend and append it to 88, then repeat: 883 / 91

Step 3:
91 goes into 883 9 times with a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 819 from 883 leaves us with 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 91

Moving on to step 4:
If we divide 647 by 91, we get 7 and a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
The remainder is 10 after subtracting 637 from 647.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 91

Let's proceed to step 5:
104 divided by 91 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 971.0
Subtract 91 from 104 to get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 91

On to step 6:
91 can be fit into 130 1 times, resulting in a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 9711.0
Subtract 91 from 130 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
The number 91 fits into 390 4 times, leaving a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 9711.4
If we take 364 away from 390, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
If we divide 260 by 91, we get 2 and a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 9711.42
If we take 182 away from 260, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
The number 91 fits into 780 8 times, leaving a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 9711.428
If we subtract 728 from 780, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
91 can be fit into 520 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 9711.4285
Subtract 455 from 520 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
If we divide 650 by 91, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 9711.42857
If we subtract 637 from 650, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
The number 91 fits into 130 1 times, leaving a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 9711.428571
If we subtract 91 from 130, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 13:
If we divide 390 by 91, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 9711.4285714
Subtracting 364 from 390 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
91 goes into 260 2 times with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 9711.42857142
Subtract 182 from 260 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 9711.42857142 with a balance of 7.8e-08.
