951310 ÷ 91 
The aim is to understand the frequency of 91 in 951310.

Advancing to step 1:
The number 91 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 91

Moving on to step 2:
The number 91 fits into 95 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 91 away from 95, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 91

On to step 3:
91 can be fit into 41 0 times, resulting in a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 41, we get 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 91

Going ahead to step 4:
When dividing 413 by 91, we get 4 with a remainder of 49.
The next digit of our result is 4. 
Result so far: 104.0
Deduct 364 from 413 and we're left with 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 91

Advancing to step 5:
91 goes into 491 5 times with a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 1045.0
Subtract 455 from 491 to get 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 91

On to step 6:
When dividing 360 by 91, we get 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 10453.0
If we subtract 273 from 360, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 7:
91 can be fit into 870 9 times, resulting in a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 10453.9
If we subtract 819 from 870, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 8:
91 goes into 510 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 10453.95
Subtracting 455 from 510 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
91 can be fit into 550 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 10453.956
Subtract 546 from 550 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
91 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10453.956
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
If we divide 400 by 91, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 10453.95604
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
The number 91 fits into 360 3 times, leaving a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 10453.956043
Subtract 273 from 360 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 13:
If we divide 870 by 91, we get 9 and a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 10453.9560439
If we subtract 819 from 870, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 14:
91 goes into 510 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 10453.95604395
Subtract 455 from 510 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 10453.95604395 with a remaining 5.5e-08.
