We divide 693633 by 91
The aim is to understand the frequency of 91 in 693633.

Step 1:
The number 91 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 91

Moving on to step 2:
91 can be fit into 69 0 times, resulting in a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Bring next digit (3) of the dividend behind the 69 and repeat the process: 693 / 91

Let's proceed to step 3:
693 divided by 91 is 7 with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 637 from 693 and we're left with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 91

Step 4:
The number 91 fits into 566 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
If we subtract 546 from 566, we get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 91

Going ahead to step 5:
91 goes into 203 2 times with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 762.0
Subtracting 182 from 203 leaves us with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 91

Let's proceed to step 6:
When dividing 213 by 91, we get 2 with a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 7622.0
Subtracting 182 from 213 leaves us 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.

Moving on to step 7:
91 goes into 310 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 7622.3
If we take 273 away from 310, we end up 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.

Let's proceed to step 8:
If we divide 370 by 91, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 7622.34
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.

Advancing to step 9:
If we divide 60 by 91, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 7622.34
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
600 divided by 91 is 6 with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 7622.3406
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
540 divided by 91 is 5 with a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 7622.34065
Deduct 455 from 540 and we're left 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.

Let's proceed to step 12:
When dividing 850 by 91, we get 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 7622.340659
Subtracting 819 from 850 leaves us 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.

Moving on to step 13:
When dividing 310 by 91, we get 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 7622.3406593
Subtracting 273 from 310 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 14:
91 goes into 370 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 7622.34065934
Deduct 364 from 370 and we're left 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.

In conclusion, the division gives 7622.34065934 with a balance of 6e-09.
