We divide 182787 by 91
The aim is to understand the frequency of 91 in 182787.

Advancing to step 1:
The number 91 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 91

Let's proceed to step 2:
91 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 91

Let's proceed to step 3:
When dividing 182 by 91, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 182 from 182, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 91

Going ahead to step 4:
If we divide 7 by 91, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 91

Going ahead to step 5:
91 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 91

Moving on to step 6:
The number 91 fits into 787 8 times, leaving a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 2008.0
Subtract 728 from 787 to get 59.
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 7:
590 divided by 91 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 2008.6
Subtracting 546 from 590 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
When dividing 440 by 91, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 2008.64
Subtract 364 from 440 to 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.

Advancing to step 9:
91 can be fit into 760 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 2008.648
Deduct 728 from 760 and we're left 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 10:
When dividing 320 by 91, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 2008.6483
Subtracting 273 from 320 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 11:
91 can be fit into 470 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2008.64835
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.

Let's proceed to step 12:
91 goes into 150 1 times with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 2008.648351
Subtract 91 from 150 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 13:
590 divided by 91 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 2008.6483516
Deduct 546 from 590 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
91 goes into 440 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 2008.64835164
Subtracting 364 from 440 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 2008.64835164 and a remainder of 7.6e-08.
