312763 ÷ 91 
The aim is to understand the frequency of 91 in 312763.

Step 1:
The number 91 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 91

Let's proceed to step 2:
The number 91 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 91

Advancing to step 3:
When dividing 312 by 91, we get 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 273 from 312 leaves us with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 91

Step 4:
91 can be fit into 397 4 times, resulting in a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 34.0
The remainder is 33 after subtracting 364 from 397.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 91

Advancing to step 5:
If we divide 336 by 91, we get 3 and a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 343.0
Subtract 273 from 336 to get 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 91

Let's proceed to step 6:
91 can be fit into 633 6 times, resulting in a remainder of 87.
The next digit of our result is 6. 
Result so far: 3436.0
If we take 546 away from 633, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 7:
When dividing 870 by 91, we get 9 with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 3436.9
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.

On to step 8:
91 can be fit into 510 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 3436.95
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.

Moving on to step 9:
When dividing 550 by 91, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 3436.956
The remainder is 4 after subtracting 546 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
The number 91 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3436.956
If we subtract 0 from 40, we 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.

Advancing to step 11:
400 divided by 91 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 3436.95604
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.

Advancing to step 12:
The number 91 fits into 360 3 times, leaving a remainder of 87.
The next digit of our result is 3. 
Result so far: 3436.956043
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.

Advancing to step 13:
When dividing 870 by 91, we get 9 with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 3436.9560439
Deduct 819 from 870 and we're left with 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:
510 divided by 91 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 3436.95604395
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.

The quotient of the division is 3436.95604395, and the remainder is 5.5e-08.
