We're dividing 38876196 by 91 
The aim is to understand the frequency of 91 in 38876196.

Moving on to step 1:
3 divided by 91 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 91

Advancing to step 2:
If we divide 38 by 91, we get 0 and a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 91

Moving on to step 3:
91 goes into 388 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 364 from 388 leaves us with 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 91

Let's proceed to step 4:
91 goes into 247 2 times with a remainder of 65.
The next digit of our result is 2. 
Result so far: 42.0
If we subtract 182 from 247, we get 65.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 91

Let's proceed to step 5:
656 divided by 91 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 427.0
Subtracting 637 from 656 leaves us with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 91

On to step 6:
91 can be fit into 191 2 times, resulting in a remainder of 9.
The next digit of our result is 2. 
Result so far: 4272.0
If we subtract 182 from 191, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 91

On to step 7:
91 can be fit into 99 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 42721.0
Subtracting 91 from 99 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 91

Going ahead to step 8:
86 divided by 91 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 427210.0
Subtract 0 from 86 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
If we divide 860 by 91, we get 9 and a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 427210.9
Subtracting 819 from 860 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
410 divided by 91 is 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 427210.94
Deduct 364 from 410 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
The number 91 fits into 460 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 427210.945
Subtracting 455 from 460 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
91 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 427210.945
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
91 can be fit into 500 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 427210.94505
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 14:
The number 91 fits into 450 4 times, leaving a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 427210.945054
The remainder is 86 after subtracting 364 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 15:
860 divided by 91 is 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 427210.9450549
Subtracting 819 from 860 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 16:
If we divide 410 by 91, we get 4 and a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 427210.94505494
Deduct 364 from 410 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 427210.94505494 with a remainder of 4.6e-08.
