We're dividing 633792 by 91 
The aim is to understand the frequency of 91 in 633792.

Going ahead to step 1:
The number 91 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 91

On to step 2:
63 divided by 91 is 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 91

Let's proceed to step 3:
The number 91 fits into 633 6 times, leaving a remainder of 87.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 87 after subtracting 546 from 633.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 91

On to step 4:
91 can be fit into 877 9 times, resulting in a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 69.0
If we take 819 away from 877, we end up with 58.
Bring next digit (9) of the dividend behind the 58 and repeat the process: 589 / 91

Advancing to step 5:
When dividing 589 by 91, we get 6 with a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 696.0
If we subtract 546 from 589, we get 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 91

Advancing to step 6:
If we divide 432 by 91, we get 4 and a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 6964.0
The remainder is 68 after subtracting 364 from 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
91 goes into 680 7 times with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 6964.7
Deduct 637 from 680 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 8:
If we divide 430 by 91, we get 4 and a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 6964.74
Deduct 364 from 430 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
If we divide 660 by 91, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 6964.747
Deduct 637 from 660 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 10:
91 goes into 230 2 times with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 6964.7472
If we take 182 away from 230, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
When dividing 480 by 91, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 6964.74725
The remainder is 25 after subtracting 455 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
When dividing 250 by 91, we get 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 6964.747252
The remainder is 68 after subtracting 182 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
91 goes into 680 7 times with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 6964.7472527
The remainder is 43 after subtracting 637 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 14:
430 divided by 91 is 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 6964.74725274
The remainder is 66 after subtracting 364 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 6964.74725274 with a balance of 6.6e-08.
