Let's divide 97649498 by 91
The aim is to understand the frequency of 91 in 97649498.

Let's proceed to step 1:
When dividing 9 by 91, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 91

Step 2:
91 goes into 97 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 91 from 97, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 91

Going ahead to step 3:
The number 91 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 91

On to step 4:
When dividing 664 by 91, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Deduct 637 from 664 and we're left with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 91

Going ahead to step 5:
91 can be fit into 279 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 1073.0
If we take 273 away from 279, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 91

On to step 6:
If we divide 64 by 91, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 10730.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 91

On to step 7:
The number 91 fits into 649 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 107307.0
If we subtract 637 from 649, we get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 91

Moving on to step 8:
The number 91 fits into 128 1 times, leaving a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1073071.0
Subtracting 91 from 128 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
The number 91 fits into 370 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1073071.4
Subtracting 364 from 370 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
60 divided by 91 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 1073071.4
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
91 goes into 600 6 times with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 1073071.406
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
When dividing 540 by 91, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 1073071.4065
Subtracting 455 from 540 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 13:
When dividing 850 by 91, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 1073071.40659
If we take 819 away from 850, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 14:
91 can be fit into 310 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 1073071.406593
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 15:
370 divided by 91 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1073071.4065934
If we subtract 364 from 370, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 16:
60 divided by 91 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 1073071.4065934
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 1073071.4065934, and the remainder is 6e-08.
