38363052 divided by 91 
The aim is to understand the frequency of 91 in 38363052.

On to step 1:
3 divided by 91 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 91

Moving on to step 2:
When dividing 38 by 91, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 91

Step 3:
91 goes into 383 4 times with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 19 after subtracting 364 from 383.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 91

Moving on to step 4:
When dividing 196 by 91, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 182 from 196 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 91

Let's proceed to step 5:
143 divided by 91 is 1 with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 421.0
Subtract 91 from 143 to get 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 91

Moving on to step 6:
91 goes into 520 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 4215.0
If we take 455 away from 520, we end up with 65.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 91

Let's proceed to step 7:
When dividing 655 by 91, we get 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 42157.0
Subtracting 637 from 655 leaves us with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 91

Advancing to step 8:
91 can be fit into 182 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 421572.0
The remainder is 0 after subtracting 182 from 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 91 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 421572.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 91, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 421572.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 421572.0 and a remainder of 0.0.
