56816 divided by 91 
The aim is to understand the frequency of 91 in 56816.

Going ahead to step 1:
The number 91 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 91

Let's proceed to step 2:
The number 91 fits into 56 0 times, leaving a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 91

Going ahead to step 3:
568 divided by 91 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 546 away from 568, we end up with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 91

Going ahead to step 4:
The number 91 fits into 221 2 times, leaving a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
The remainder is 39 after subtracting 182 from 221.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 91

Advancing to step 5:
When dividing 396 by 91, we get 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 624.0
If we take 364 away from 396, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 6:
320 divided by 91 is 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 624.3
Subtract 273 from 320 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
91 goes into 470 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 624.35
Subtracting 455 from 470 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
91 can be fit into 150 1 times, resulting in a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 624.351
The remainder is 59 after subtracting 91 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 9:
91 can be fit into 590 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 624.3516
Subtract 546 from 590 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
91 can be fit into 440 4 times, resulting in a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 624.35164
If we subtract 364 from 440, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
91 can be fit into 760 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 624.351648
If we take 728 away from 760, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
When dividing 320 by 91, we get 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 624.3516483
If we subtract 273 from 320, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
91 can be fit into 470 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 624.35164835
If we take 455 away from 470, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 624.35164835 with a remaining 1.5e-08.
