91333641 divided by 228 
The aim is to understand the frequency of 228 in 91333641.

Let's proceed to step 1:
The number 228 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 228

Going ahead to step 2:
228 goes into 91 0 times with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (3) from the dividend and append it to 91, then repeat: 913 / 228

Advancing to step 3:
228 goes into 913 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 912 from 913 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 228

Let's proceed to step 4:
The number 228 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 13 to get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 228

Let's proceed to step 5:
133 divided by 228 is 0 with a remainder of 133.
Put 0 as the next digit of the answer. 
Result so far: 400.0
If we subtract 0 from 133, we get 133.
Bring next digit (6) of the dividend behind the 133 and repeat the process: 1336 / 228

Advancing to step 6:
When dividing 1336 by 228, we get 5 with a remainder of 196.
Write down 5 as next digit of the result. 
Result so far: 4005.0
The remainder is 196 after subtracting 1140 from 1336.
Bring next digit (4) of the dividend behind the 196 and repeat the process: 1964 / 228

Let's proceed to step 7:
The number 228 fits into 1964 8 times, leaving a remainder of 140.
The next digit of our result is 8. 
Result so far: 40058.0
The remainder is 140 after subtracting 1824 from 1964.
Include the next digit (1) from the dividend after 140, then repeat: 1401 / 228

On to step 8:
228 goes into 1401 6 times with a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 400586.0
If we subtract 1368 from 1401, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
The number 228 fits into 330 1 times, leaving a remainder of 102.
The next digit of our result is 1. 
Result so far: 400586.1
Deduct 228 from 330 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 10:
The number 228 fits into 1020 4 times, leaving a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 400586.14
If we take 912 away from 1020, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 11:
228 goes into 1080 4 times with a remainder of 168.
The next digit of our result is 4. 
Result so far: 400586.144
Subtracting 912 from 1080 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 400586.144, with a leftover of 0.0168.
