936533 divided by 91 
The aim is to understand the frequency of 91 in 936533.

On to step 1:
91 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 91

Moving on to step 2:
When dividing 93 by 91, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 91 from 93.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 91

Advancing to step 3:
If we divide 26 by 91, we get 0 and a remainder of 26.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 26 and we're left with 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 91

On to step 4:
265 divided by 91 is 2 with a remainder of 83.
Write down 2 as next digit of the result. 
Result so far: 102.0
If we subtract 182 from 265, we get 83.
Fetch the next digit (3) from the dividend, attach it to 83 and continue: 833 / 91

Advancing to step 5:
833 divided by 91 is 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 1029.0
Subtract 819 from 833 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 91

Let's proceed to step 6:
When dividing 143 by 91, we get 1 with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 10291.0
If we subtract 91 from 143, 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.

Let's proceed to step 7:
The number 91 fits into 520 5 times, leaving a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 10291.5
If we subtract 455 from 520, we 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 8:
650 divided by 91 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 10291.57
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.

On to step 9:
The number 91 fits into 130 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 10291.571
Subtracting 91 from 130 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 10:
91 goes into 390 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 10291.5714
Subtract 364 from 390 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
When dividing 260 by 91, we get 2 with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 10291.57142
Subtracting 182 from 260 leaves us 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.

Moving on to step 12:
91 goes into 780 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 10291.571428
Subtract 728 from 780 to 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.

Let's proceed to step 13:
91 goes into 520 5 times with a remainder of 65.
The next digit of our result is 5. 
Result so far: 10291.5714285
If we subtract 455 from 520, we 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 14:
If we divide 650 by 91, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 10291.57142857
Subtract 637 from 650 to 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.

The quotient of the division is 10291.57142857, and the remainder is 1.3e-08.
