We're dividing 381032 by 91 
The aim is to understand the frequency of 91 in 381032.

Going ahead 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

Moving on to step 2:
The number 91 fits into 38 0 times, leaving a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 91

On to step 3:
The number 91 fits into 381 4 times, leaving a remainder of 17.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 364 from 381, we get 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 91

Going ahead to step 4:
91 can be fit into 170 1 times, resulting in a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we take 91 away from 170, we end up with 79.
Append the next digit (3) from the dividend to 79 and continue with: 793 / 91

Step 5:
793 divided by 91 is 8 with a remainder of 65.
Write down 8 as next digit of the result. 
Result so far: 418.0
Subtract 728 from 793 to get 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 91

On to step 6:
91 can be fit into 652 7 times, resulting in a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 4187.0
If we take 637 away from 652, 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.

Step 7:
When dividing 150 by 91, we get 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 4187.1
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.

Let's proceed to step 8:
When dividing 590 by 91, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 4187.16
If we subtract 546 from 590, we 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.

Let's proceed to step 9:
If we divide 440 by 91, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 4187.164
If we take 364 away from 440, we end up 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.

On to step 10:
91 can be fit into 760 8 times, resulting in a remainder of 32.
The next digit of our result is 8. 
Result so far: 4187.1648
Subtracting 728 from 760 leaves us 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.

Moving on to step 11:
91 can be fit into 320 3 times, resulting in a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 4187.16483
Deduct 273 from 320 and we're left 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.

Let's proceed to step 12:
When dividing 470 by 91, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 4187.164835
Subtract 455 from 470 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
91 goes into 150 1 times with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 4187.1648351
If we subtract 91 from 150, we 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.

Step 14:
91 goes into 590 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 4187.16483516
If we take 546 away from 590, we end up 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.

The final outcome is 4187.16483516, with a leftover of 4.4e-08.
